processes to solubilize copper (and by-product cobalt) whilst rejecting the iron predominantly as a non-hydrated haematite residue. Total pressure oxidation of copper concentrates is a process option, which has been tested previously on a number of different concentrate types. The attractiveness of this route for treatment of copper-gold ores, in particular, has been recognised3. The process

Extraction of Gold Ores by These Processes Xinhai

This gold extraction process is to float the gold into copper, lead concentrate, and then extract the gold from these concentrates. Therefore, it is a more economical and reasonable process for the extraction of gold ore with non-ferrous metals. This gold extraction process can realize the comprehensive utilization of metal, and enrich the gold as much as possible into the sulfide minerals.
