Diversified junior Walkabout Resources is hoping to complete a prefeasibility study (PFS) on its Takatokwane coal project, in Botswana, by mid-2014.

Last month, the Perth-based company signed a memorandum of understanding (MoU) with technology firm Coalswana to complete an integrated PFS and bankable feasibility study (BFS) for Takatokwane.

The study will not only incorporate an underground mining operation at Takatokwane, but will also look at the possibility of developing a coal-to-liquids (CTL) beneficiation plant at site.

Under the terms of the MoU, Coalswana will fund the integrated studies and the mining licence application, and in return, Walkabout will issue the London-based firm with a five-year convertible note.

Walkabout MD Allan Mulligan told Mining Weekly Online on Wednesday that the agreement with Coalswana not only removed the PFS costs from Walkabout’s accounts, but also de-risked the project and brought a new marketing avenue for the Takatokwane project.

The integrated development would see Walkabout investing between A$40-million and A$60-million to develop an underground mining operation at Takatokwane, capable of supporting the CTL plant being built, and funded, by Coalswana.

The underground mine would also have the capacity to export between 1-million and 1.5-million tonnes a year of coal to South Africa.

“The coal-to-liquids plant uses not only primary product, but also middling product, which we would consider our waste pile of lower quality coal. So developing an initial five-million-tonne-a-year operation could supply both the CTL plant and an export operation,” Mulligan said.

He added that Walkabout was currently contemplating a life-of-mine offtake agreement with Coalswana, and added that the company had not closed the door on potentially owning an equity share in the CTL plant.

Once the integrated PFS had been completed, Coalswana would conduct its own BFS on the proposed CTL plant, while Walkabout’s focus would remain on the underground operation.

“The bankable feasibility studies will be conducted if both developments are found to be viable. And if only one proves viable, then we will focus on that one,” said Mulligan.

In the longer term, the Takatokwane operation could be developed into a multi-mine project delivering some 20-million tonnes of coal a year, and Mulligan said that the major markets for this amount of product would likely be China or India.

The development of the larger scale operation, which would consist of opencast mines, was dependent on the development of a suitable rail line from Botswana to Namibia.

Dolomite is one kind of carbonate mineral which includes iron dolomite and manganese dolomite. The dolomite can be used in building materials, porcelain, glass and refractory after crushing. In chemical industry, agriculture, environmental protection, energy conservation, etc, the dolomite is also in a great demand. In zenith company, you could find the appropriate equipment for crushing and grinding dolomite materials.

Dolomite Crushing Process

Big Dolomite materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After first crush, the material will transferred to impact crusher by belt conveyor for secondary crush; the crushed dolomite materials will then transferred to vibrating screen for separating. After separating, the parts that can meet standard will be transferred away as final products, while the other parts will be returned to impact crusher, thus forming a closed circuit. Size of final products can be combined and graded according to your specific requirement.

Grind the dolomite to ultrafine mill’s process

Vibrating feeder will feed dolomite materials into grinding chamber evenly and gradually. After being grinded, the powder will be blowed to cyclone by blower. Then the dolomite material will be transferred to storage room through pipes, and then will be discharged as final products. The whole process works in a negative pressure environment.

India is rich in various mineral resources and it is an important mineral processing market. With the development of local economy, lots of mineral processing plants are built there.Zenith has built our oversea office in India for many years and we have numerous customers there, the market is quite mature.
Early of 2009, one customer from India got in touch with us, he told us that he was working in one mining company and his boss had one milling plant made up of Raymond mill and one primary 16″×10″ jaw crusher. They would like to use this plant to grind calcium carbonate powder, but the final products could not meet their demand. They hoped that the final product size should be reach 5-10 micron and the capacity should be about 1tons per hour. Now they would like to built one that able to meet their requirements.
After good communication with the customer, we knew their requirements well. And our engineer suggest them adopting Zenith SCM Ultrafine grinding mill. Raw materials of 12″-14″ size are firstly crushed by the client’s jaw crusher down to 2″ and then enter into our hammer crusher. Crushed to less than 0.4”, the materials will be fed to the SCM milling machine. When powders discharged from the milling machine, they meet customers’ requirements well. The mill was installed since 2009 and it is running perfect in India now.

As we all know,copper ore is mined both underground and on the surface. Large excavations formed by surface mining are called open-pit mines. Most of the copper ores mined today are oxide or sulfide ores.From the mines, copper ore is taken to mills, where it is crushed and finely ground in preparation for refining. The method of refining varies with the type of ore.In the case of copper-oxide ores, the copper is usually leached (dissolved) from the ore with a solution of sulfuric acid.

The copper can be recovered from the leaching solution through electrolysis. In this process, a direct electric current is set up between positive and negative electrodes placed in the solution. The negative electrodes, called cathodes, are usually made of thin sheets of pure copper and the positive electrodes, called anodes, are usually made of lead. The electric current causes the copper in the solution to be deposited on the cathodes as a coating of pure copper.Another method is to pass the solution over scrap iron; a chemical reaction causes the copper to be deposited on the iron. The copper is separated from the iron by methods used to refine copper-sulfide ores (many of which also contain iron).

Copper-sulfide ores are first treated by a process called flotation. In this process, bubbles are produced in a mixture of ground copper ore, water, and chemical reagents. The particles of copper-bearing minerals in the ore stick to the bubbles and float to the top of the mixture, where they can be skimmed off.The copper-bearing minerals are roasted to drive off a part of the sulfur. The resulting product is smelted, yielding a molten combination of copper sulfate and iron sulfide called matte. Some light impurities in the matte combine to form slag, which is removed. The matte is then poured into a converter, where air is forced through it to burn out the remaining sulfur and to oxidize the iron. At this stage, most of the remaining impurities, including the oxidized iron, float to the top of the matte to form more slag, which is poured off.

The metallic copper that is left at the bottom of the converter is known as blister copper. It is very pure, but further refining is necessary to remove impurities consisting of small amounts of gold, silver, and other precious metals.This refining is done electrochemically, using a process similar to the one used with oxide ores. In this case, however, the anode is molded from blister copper and decomposes during electrolysis. The direct electric current that flows between the electrodes placed in an electrolytic tank transfers the copper of the blister copper anode onto the cathode. The precious-metal impurities collect at the bottom of the tank.A significant portion of the copper produced today is refined from copper scrap. Copper produced from scrap is called secondary copper.

Extracting Copper From Its Ores

The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.

Copper Underground Mining

For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material. Large track-mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore-dressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 metres (3,300 feet) below the surface, and tunnels are extended to the ore body. The ore, broken by drilling and blasting, is hoisted through the shaft and conveyed to the processing plant. In some cases, primary crushing takes place underground; in others, a ramp and trucks carry ore to the surface.

Conduct Copper Mine Process

The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces.

  • The copper ions in the chalcopyrite are reduced to copper sulphide (which is reduced further to copper metal in the final stage).
  • The iron in the chalcopyrite ends up converted into an iron silicate slag which is removed.
  • Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas. This is used to make sulphuric acid via the Contact Process.

Mining machinery is an industry that specializes in manufacturing all kinds of rock mining and smelting machines. Because of economic development and increase of consumption demand and lubricate lucrative profit, many enterprises flock into this industry. But the increase of number of companies disperses the target customer market, so that the profit margin shrinks dramatically, as a result of which, many manufacturers copy what already exists in the market, but not innovate the technology and increase science and technology content.

Many people may think that the price of large-sized mining machinery such as sand maker should have little fluctuation since they think there are few factors influencing it. But the experts say that as a matter of fact, its price is affected by many factors. You shall never believe it will not fluctuate as long as fixed. Once you think like this, it may cost you a lot when purchasing sand making machine. So let us find out what factors affect its price.

  • It is obvious that different price leads to different stone crusher price. Famous brand will certainly give you guarantee from quality as well as after-sales service, and it will surely cause price fluctuation.
  • Different specifications. Of course, the purpose is different so that the specifications will be not the same, and the difference will shows in tariff. So we recommend that when you are purchasing mining equipment, you should always choose according to your own need.
  • Different technical data will result in dissimilar mining facilities. This is the same with the above point because new and old type of machine has distinct technical data, so you will of course have to pay more for the new type.

You know there still many other factors that have an effect on the money that you should pay for what you purchase. So when you are choosing one and the cost is not the same, you are advised not to panic, and you may choose to consult from some big companies and purchase after market research. Especially that the requirement for mining equipment is going higher and higher, such as the price should be low, the performance should be excellent and after-sales service should be guaranteed, all these issues can not be solved by small brand, as a result, we recommend that you had better focus on the big and famous band,such as Zenith and you can trust us.
