Lead for recycling may be in the form of scrap metal (roofing sheet, for example), or compounds of lead, such as the pastes from lead-acid batteries. Clean metallic lead can be melted and refined directly, but compounds and lead alloys require smelting, using processes similar to those used with lead ores.

Concentrating and smelting is preferred to direct smelting until the grind size falls below about 10 μm, at which point direct smelting becomes the preferred route at all grades between 0.1% and 1.0% copper. In the case of nickel, concentrating and smelting is also the preferred route provided no additional grinding of the ore is required as ...

Apr 11, 2017· The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining.
Step By Step Copper Smelting Process In Palabora Mines Pyrometallurgy, or smelting, usually used in the smelting process of copper ore with sulfide and iron sulfide minerals. The concentrate is dried and fed into a furnace.
The second step, involving either smelting or leaching, removes a large proportion of impurity elements—in particular iron and, in the case of sulfide ores, sulfur. The final step, refining, removes the last traces of the impurity elements and produces a copper product of 99.99 percent purity.
Artisanal and Small-Scale Gold Mining Without Mercury. ... Although many miners use mercury in artisanal and small-scale gold mining, it is possible to safely and economically recover gold without it. ... Using Concentration Methods. Concentration means increasing the amount of gold in ore or sediment, by selectively removing lighter particles.
Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are The major steps in the extraction of copper are
