Processes - extraction, mining, smelting, refining ...

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).

Tungsten: extraction and processing-Metalpedia

The common tungsten extraction methods are surface (or open pit) mining and sub-surface (or underground) mining, or a combination of both. Modern tungsten processing methods dissolve scheelite and wolframite concentrates by an alkaline pressure digestion, and tungsten can also be recycled from Scrap.

Nickel / cobalt mining extraction procedures

NICKEL CHLORIDE PROCESS. At present, the large cobalt and nickel ores are in the process of clear depletion and the main ores of these two metals are constituted by minor mineral concentrations in ores formed by different metals. This requires the mineral extraction processes to be modified in each case.

Titanium Extraction and Refining Titanium

Processing the Material. So far, this process is not too far removed from other mining and extraction operations. However, this is where things get a little more difficult. Titanium processing is done with something called the Kroll Process which, even when it was first introduced in the 1930s, has never been the most efficient way to go.

Mining and Extraction: Oxide Ores - processes

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

Nickel / cobalt mining extraction procedures

The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a “speiss”, rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air.
