Copper Precipitation & Cementation using Scrap Iron

In the search for lower cost methods of recovering copper, the use of sponge iron or particulate iron (as distinguished from iron powder used in powder metallurgy) as precipitants in place of tin cans, detinned scrap iron, or scrap iron is an intriguing possibility. The relatively faster copper precipitation rate obtained with particulate iron as compared to scrap iron promises economic and

Tellurium extraction from copper electrorefining slimes

The process comprises digesting the slimes in sulphuric acid to form soluble tellurium sulphate, and the solid fraction is removed by filtration. Metallic copper is then added to the filtrate to form a copper-tellurium cementation product containing finely divided tellurium particles. Some metallic silver is also precipitated with the tellurium.
