Zondereinde Mine, South Africa

The Zondereinde mine is an underground operation located in Limpopo Province, South Africa. It is adjacent to the Amandelbult mine owned by Anglo Platinum.

The mine consists of two reefs namely the Merensky reef and the UG2 reef, and is spread over 625ha with a strike length of 8km. It is 100% owned by Northam Platinum Limited. sand making production line

The mine primarily produces platinum, palladium, rhodium and gold. It has an estimated life of 18 years.

Operations at the mine were halted in July 2010 when 5,000 miners went on strike following an accident that led to two deaths. The one-and-a-half month strike resulted in a loss of R380m to the company. Operations resumed on 19 October 2010.

Reserves

The Zondereinde mine holds 9.2Moz of reserves and 30.1Moz of resources. The total proven and probable reserves at the Merensky reef are 18.43mt graded at 5.57g/t 3PGE (platinum, palladium and rhodium) +Au.

The UG2 reef contains 43.63mt of proven and probable reserves graded at 4.6g/t 3PGE+Au. The total measured, indicated and inferred resources at the Merensky and UG2 reefs are estimated to be 71.55mt and 89.14mt respectively with grades of 6.96g/t 3PGE+Au and 4.91g/t 3PGE+Au respectively.

Geology

The mine lies within the northern section of the western limb of the Bushveld sequence. Both the Merensky and UG2 reefs are well-developed narrow tabular ore bodies. Lateral continuity is well established across the mine lease area.

"The mine lies within the northern section of the western limb of the Bushveld sequence."

The Merensky reef includes two sub-facies including the normal reef sub-facies and the local pothole sub-facies.

The local pothole sub-facies is further segmented into three different types of reef the NP2 reef, P2 reef and the footwall P2 (FWP2) reef. Among the three reefs, the footwall P2 (FWP2) reef has been historically considered to be un-mineable. stone production plant

The UG2 reef hosted between 20m and 40m below the Merensky reef has more consistent features.

As the reef disturbances in UG2 are insignificant it is not segmented into multiple facies units. The UG2 reef comprises three layers of chromitite that are separated by a 15cm thick pyroxenite. The primary member is approximately 80cm thick while the other leading members are on an average 20cm thick.

Mining

Typical drill and blast narrow tabular reef mining techniques are used at Zondereinde underground mining. A conventional breast mining layout is implemented.

A vertical distance of 63m is maintained between the levels, resulting in a raise length of 180m due to the 200 dip of the ore body. Six panels of 30m are created for every raised connection.

Through the strike gullies that incline at 10° above strike, the ore is transported to three ore-passes handled via a dip gully. The ore-passes are attached with radial-door control chutes. Battery powered electric locomotives that pull spans of eight hoppers, transport the broken ore to the main shaft.

"The mine consists of two reefs namely the Merensky reef and the UG2 reef."

To provide access to the underground workings, a twin shaft system is placed at depths ranging from 1,294m to 2,112m. The No 1 shaft has a diameter of 8.5m and continues to 12 levels. The second 9.15m diameter shaft extends to eight levels.

The shafts are 90m apart and are connected at an intermediate pump chamber at a depth of 1,019m and also at levels 4, 6, 7, 8 and 9. Access below the 12th level is provided through a decline that is equipped with a conveyor belt system.

The rock handling facilities are separate for the Merensky and UG2 reefs. Mining activities are carried out using hydro-powered equipment including rock drills and high pressure waterjets along with electric scraper winches.

Processing

Processing of both Merensky and UG2 ores is carried out in separate plants designed to process sulphide ores. It involves a four-stage beneficiation process. The concentrates produced from the plants are blended in the feed tank in a slurry form.

It is then filtered and dried at the smelter. The granulated converter matte is delivered to the base metals removal (BMR) plant. In the BMR plant, the nickel and copper cathodes are separated from the high grade PGM concentrate. The final crystalline nickel sulphate and copper cathode are delivered to the local customers.

Chile's Codelco to invest $16bn 2011-2015

SANTIAGO - Chile's state copper giant Codelco will invest over $16-billion between 2011-2015 and expects copper prices to remain strong in the long-term, the miner said on Thursday. Sand Making Machine

CEO Diego Hernandez said he expected copper demand from top consumer China to remain strong, and forecast tight supply in 2011 and 2012 would underpin prices.

"We think supply and demand should remain tight this year and next," Hernandez said. "We think prices will be pressured higher this year and next.

"As Chinese urbanization continues in the coming years, and everything indicates it will, demand for copper will remain at the levels we have seen."

Hernandez said the company would invest a record $3.2 billion in 2011 and will step up investment further in 2012-2013. He said the company was increasing investment in exploration, and was eyeing exploration projects in Brazil and Ecuador. Salt Crusher

He said Codelco could issue between $500 million and $700 million in debt or recapitalize profits in 2011, but said the state giant's debt levels should remain below $9 billion for it to hold on to its investment grade.

In addition, SBM supply stationary crushers, such as Symons cone crusher, impact crusher, PE jaw crusher, JCE jaw crusher, hammer crusher, and mobile crusher. SBM crusher is you best choice for crushing calcite.

Calcite Grinding Plant

SBM is a professional manufacturer of calcite grinder mill and calcite grinding plant. The commonest calcite grinding millis SBM MTM trapezium mill. Besides, SBM can supply MTW trapezium mill, raymond mill, ball mill, coarse powder mill, etc and design kinds of whole grinding plant on the basis of customers' requirement. SBM grinding mill is your best choice of grinding calcite.

Calcite belongs to the calcite group, a group of related carbonatesthat are isomorphous with one another. They are similar in manyphysical properties, and may partially or fully replace one another,forming a partial solid solution series. All members of the calcitegroup crystallize in the trigonal subdivision of the hexagonal system(as rhombohedrons and scalenohedrons), have perfect rhombohedralcleavage, and exhibit a strong double refraction in transparentrhombohedrons.

Calcite is the one of the most common minerals onearth. It occurs in a seemingly unlimited variety of shapes and colors.It constitutes a major portion of many of the earth's rocks.

Calciteand Aragonite are polymorphous to each other. Although Calcite andAragonite contain the same elements, they differ in crystal structure.Calcite forms trigonal crystals, whereas Aragonite forms orthorhombiccrystals. Sometimes, the crystals of Calcite and Aragonite are toosmall to be detected, and it is only possible to distinguish these twominerals by complex scientific tests. Since the true identity of thesemicrocrystalline forms is not known, they are simply labeled as"Calcium Carbonate". This definition accurately includes both Calciteand Aragonite.

A microcrystalline type of Calcite in globularform is common in certain regions. This Calcite forms fromprecipitating calcium-rich water inside caverns or on limestone cliffs.It exists in the form of stalagmites, stalactites, and strange globulargrowths. These growths constantly accumulate, forming layers. They arefrequently impure, trapping in organic matter such as leaves, twigs,and moss as they accumulate. Because of their impure status, they areclassified by some as rocks. These calcareous growths have designatednames based on their shape, habit, or formation (see the variety fieldfor a list of the names). Most of these growths are Calcite, but someare crystallized as Aragonite. The environment of formation, however,can be a key guide to whether the mineral crystallized as Calcite orAragonite. Aragonite will only form these growths by hot springs; allother growths are Calcite.

Aggregates are the raw materials for construction buiding, and they are inert granular materials such as sand, small-size gravel, or crushed stones. They along portland cement and water, are an essential ingredient in concrete making. Aggregate can be divided into two distinct categories-coarse and fine. Coarse aggregates are particles greater than 0.19 inch (4.75 mm), but generally range between 3/8 and 1.5 inche (9.5 mm to 37.5 mm) in diameter. Gravels constitute the majority of coarse aggregate used in concrete. Fine aggregates generally are consist of natural sand or crushed stones with most particles passing through a 3/8-inch (9.5-mm) sieve of vibrating screen.

Aggregate Crusher

There are several types of crushers to be choosed as stone aggregate crusher machine used in stone aggregate crushing plant.
Jaw crusher usually is used as primary crusher for aggregate primary crushing. Impact crusher also can be used secondary stone aggregate crushing equipment in aggregate crushing process. Because aggregate for road construction building is strict in shape, so we also need vsi crusher in complete stone aggregate plant, it can crush crushed stones and sand into cubic pieces. Cone crusher, roll crusher, gyratory crusher and hammermill cruhser is also used in quarry aggregate plant.
Then text step is screening process. According to the requirements of size, choose the right screening machine to screen out the eligible aggregate.
Aggregate washing machine is also essential mining machine in stone aggregate production line.

Aggregate crushing plant

Natural gravel or sand are usually dredged or dug from a pit, river, lake, seabed or mountain. Crushed aggregate is produced by crushing quarry rocks, boulders, cobbles, or large-size gravels. Recycled concrete is a viable source of aggregate and has been satisfactorily used in soil-cement, granular subbases, and in new concrete. Aggregate processing consists of crushing, screening, and washing the aggregate to obtain proper cleanliness and size. If necessary, a benefaction process such as jigging or heavy media separation can be used to upgrade the quality.

The Big materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for the primary crushing. After first crushing, the material will transferred to impact crusher or cone crusher by belt conveyor for secondary crushing; the crushed materials will then transferred to vibrating screen for separating. After being separated, the parts that can meet standard will be taken away as final products, while the other parts will be returned to cone crusher or impact crusher for re-crushing , thus forming a closed circuit. Size of final products can be combined and graded according to customer’s specific requirement. We can also equip dust catcher system to protect environment.

The start of production of cubical aggregate will influence the economic development of the region positively and will improve housing and road construction.

coal crushing plant applied for coal processing

Coal Classification
Coal can be classified into subbituminous coal, lignite, anthracite, and bituminous coal. Of the four kinds of coal, anthracite is the hardest and has the highest carbon content.

Coal Crusher Applied for Coal Processing
The whole process to deal with coal is as follows: The raw coal is first sent to a belt conveyor to a preparation plant located at the mining site. The plant is responsible for removing some unwanted materials such as dirt, rock, ash, and sulphur in order to increase the coal's heat value. Some coal processing equipment is indispensable in this process.

Coal crusher can resize the coal stones so that they can be easily processed. In general, the coal's Mohs hardness is below 5. The miners usually use jaw crusher, impact crusher and hammer crusher to handle it. After the crushing process, the coal will be conveyed via belt conveyor to the vibrating screen so as to sieve out the coal by size. In addition, in order to remove water from the products, dewatering screen is necessary.

Shibang Machinery has over 50 years of manufacturing experience in coal crushing plant. As a major coal crusher supplier, we provide equipment for power plants and coke ovens, crush limestone for blast furnaces, and crush a variety of materials for industrial uses. Besides, as one of the largest exporter of coal crushers and some related spare parts, Jinjin Mining Machinery has designed and developed various crushers, which are widely applied for material crushing and processing in more than 100 countries around the world.

In order to satisfy customers' needs, the coal must be crushed into suitable sizes. According to the particle size, the crushing process can be divided into coarse grain (the crushing to 50mm and above), medium grain (crushed into 25-6mm), fine grain (crushed into 6-1mm), and superfine grain(1mm or less). In order to fit in with different crushing processes, primary coal crusher, secondary coal crusher and tertiary coal crusher are needed.

Coal Crusher Applied for Power Station Boiler
Power station boiler mainly provides steam to the turbine generator in thermal power plant. Fuel is burned in the boiler and releases heat energy, and heat transfers through the metal wall of the boiler water into a certain pressure and temperature of superheated steam, then steam into the turbine, the generators driven by the turbine. The world total thermal power generation capacity is about 70%, and in China the capacity reaches up to 80%. Thus, the boiler plays a significant role in reducing energy consumption and boosting the development of national economy. Most of station boilers use coal as the main fuel, so coal crusher now becomes the most commonly used crushing equipment to crush coal in thermal power plant. Jinjin coal crusher has been widely applied in the station boiler system owing to its unique advantages.

With more than 50 years' professional manufacturing experience, shibang Machinery has now taken the leading position in mining machinery industry. Moreover, we are always ready to meet new challenges. We are committed to providing quality products with low operation costs for customers.

mica crusher in uae and doubai

Mica is invaluable in the electrical industry because of its unique combination of physical, chemical and thermal properties, low power loss factor, dielectric constant and dielectric strength. Dieletric strength is the ability to withstand high voltage without puncturing. Mica is invaluable in the electrical industry because of its unique combination of physical, chemical and thermal properties, low power loss factor, dielectric constant and dielectric strength.

The Mica World Resources

crusher in UAE crushers
India is the leading producer of muscovite mica followed by Brazil. Other producing countries are the USA, Tanzania, Rhodesia and Argentina. The USA generally produces scrap mica. The leading producers of phlogopite mica are Malagasy Republic and Tanzania whose average annual productions are 1,000 tonnes and 300 tonnes respectively. Small production of phologopite is reported from Canada, Tanzania and India.
The Mica Industrial Applications
Sheet mica is used in a number of electrical and electronic appliances in different shapes and sizes. As an insulating material it is used in equipment like condensers, transformers, sheostats, radio and electronic tubes and radar circuits. It is used in the form of washers, discs, tubes and plates.
Nowadays mica is finding increasing use in equipment that encounters very high temperatures like rockets, missiles and jet engine ignition system. Phlogopite is used in spark plugs. Sheet mica, however, is not always available in required size as demanded by the industry.
Great progress has been achieved in making built-up mica called micanite. Mica films are placed with alternate layers of binding materials like shellac, alkyl, or silicon resin and then pressed and baked. Micanite is in common use now. It is convenient to cut or punch micanite according to requirements.
In the electronic-field, natural mica is mainly used in the manufacture of capacitors such as bridge-spacers in electronic valves and as panel-board where heat-resistance and low-loss peoperties at high frequencies are required. In such delicate equipment, mica of thinness varying from 0.015 inch and below are used. The mica of thickness in the range of 0.007" to 0.015" is used in bridge-spacers. Even thinner films, between 0.004" to 0.006", are used as backing plates for capacitors and further thinner films in the range of 0.0007" to 0.002" as dielectric. The splittings of such fine thickness are made with the help of pin and knife only. So you can find it the mica needs to be crushed.
Waste or scrap mica is used invariably in the form of ground mica. The uses of ground mica depend largely upon its appearance and lubricating properties. Both of these characteristics are affected by the methods of grinding as well as teh purity and nature of the scrap.
Before you use the mica, you need to crush or mill it. SBM supply the mica crusher and mica grinding mill: mica jaw crusher in doubai, mica impact crusher, mica cone crusher, vsi mica crusher, mobile mica crusher, trapezium mica grinding mill, mica ultrafine grinding mill, mica ball mill grinder etc.
