Extraction Of Copper | Mining, Concentration, Smelting ...

The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Iron in Chalcopyrite is removed as Iron silicate slag. Most of the sulfur in Chalcopyrite turns into Sulphur dioxide (SO2).

COPPER(II) EXTRACTION FROM AMMONIA LEACH SOLUTION

Copper(II) extraction from ammonia leach solution 329 more costeffective, because it requires less stages comparing to the first way of separation. The concept of coextraction (selective stripping) was used for many metal couples. It was also adopted in ammonia systems for CuNi separation.

Nickel processing |

From sulfide ores. Because the conversion of nickel sulfide directly to metal would require an extremely high temperature (in excess of 1,600 °C [2,910 °F]), the removal of sulfur at this stage of the converting process is controlled in order to produce the 70–75 percent nickel matte, which has a lower melting point.
