Reduction of Metals (Extraction from Ore) 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. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain ...

An extra benefit would also be the co-extraction of zinc which is significant available in these copper concentrates produced form bottom ash. The consortium aims to refine this copper and zinc into its pure metals by the PCR process. Through the years the PCR process made several iteration and now consists of a physical separation step (sensor sorting) followed by the hydrometallurgical ...

The oxidizing roasting cinder—containing 16.9% Pb, 30.5% Zn, 10.3% Fe and 25.1% S—was obtained from a Pb-Zn sulfide ore in the Hanyuan area of China by a flotation-rotary kiln oxidizing roasting process. Anglesite and lead oxide were the main Pb-bearing minerals, while zinc sulfate, zinc oxide and zinc ferrite were the main Zn-bearing minerals.

Mining waste containing metals is generated during the extraction and processing of metal ores. This waste can be considered a valuable secondary resource containing base metals (lead, zinc and copper) and rare metals (gold and silver). But the presence of elements that are dangerous for the environment with threats to the air, soil and water, must be taken into account.
