A method of stoping in which ore is removed in slices, or lifts, and then the excavation is filled with rock or other waste material (backfill), before the subsequent slice is extracted. Cut-off Grade The lowest grade of mineralized material considered economic; used in the calculation of the ore reserves in a given deposit. Cut-Value Applies to assays that have been reduced to some arbitrary
The simple answer is that ferrous metals contain iron and non-ferrous metals do not. The more in-depth answer is that ferrous metals and non-ferrous metals each have their own distinctive properties. These properties determine the applications they are most suited for. Non-ferrous metals have been used since the beginning of civilization. The discovery of copper in 5,000 BC marked the end of
Discovering Metals— A Historical Overview ore is a natural mineral that can be mined and treated for the extraction of any of its compo-nents, metallic or otherwise. The metallic com-ponent of copper sulfide minerals is copper. Sulfur is one of the nonmetallic elements. Ex-traction of copper from copper sulfide ores pro-vided ancient man with another source of cop-per. Once extraction
We've heard stories of PM companies paying rates up to ten times lower than their actual value. It hits home for us, and we hear it all too often. Many don't realize that, given the right tools, refining precious metals can be done in your own home, usually saving hundreds and often thousands of dollars (and frustration). 2. You'll have total control over your PMs. This is hugely important to
While the method of this invention has been described above with respect to smelting of copper sulfide ore, it will be apparent to those skilled in the art that the method is effective also for the smelting of other ores of sulfides of other non-ferrous metals, such as nickel, having properties similar to those of copper.
Refining with flame is one of the oldest methods of refining metals. Mentioned even in the bible, refining by fire is the preferable method for larger quantities of gold. In ancient times, this form of refining involved a craftsman sitting next to a hot fire with molten gold in a crucible being stirred and skimmed to remove the impurities or dross that rose to the top of the molten metal. With

Here they are treated for complete elimination of base metals, and the platinum metals are brought into solution for their separation and individual refining. The solutions handled are usually highly concentrated, extremely valuable and very corrosive. Handling is therefore carried out by employing the simplest possible methods, including siphoning and gravity draining, and use is made of
Concentration of ore: In this metallurgical operation, the ore is concentrated by removing impurities like soil etc. The process involves the crushing and washing of ore. Calcination or Roasting of ore: The concentrated ore is now heated in the presence of air. The process of roasting is performed to remove moisture, CO 2, impurities of sulphur, arsenic. Ferrous oxide is also oxidized to
However, there are places where aluminium ore has to be mined from deep underground which require underground mines to be built to get at it. One of the deepest mines is the Cheremkhovskaya-Deep mine in the Urals in Russia, its shafts run 1550 metres deep. Alumina Production . The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a

The eddy current separation method usually sorts this non-ferrous scrap. Eddy current separation takes the principles of electromagnetic induction in conducting materials, to separate non-ferrous metals by their different electric conductivities. The main principle is that 'an electrical charge is induced into a conductor by changes in magnetic flux cutting through it'. Moving permanent
There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. Extraction using carbon.
