extraction of sliver from concentrated copper
WO2015171010A1 Process of extracting gold and silver
The invention relates to a process for the extraction of gold and silver from ores and mining by products. The process according to invention consists in treating ores and mining residues having a content of 0.5 12 ppm Au with a solution of ammonium thiosulphate, recycled at a temperature of 15 25°C the filtrate resulting after solubilization is subjected to an electrolytic extraction
How Extraction of Copper from Copper Pyrites? QS Study
Extraction of copper from copper pyrites involves the following steps Crushing and concentration. The ore is crushed and then concentrated by froth floatation process. The ore obtained from mines are broken down into little piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation procedure.
Recycling WEEE: Extraction and concentration of silver
Silver precipitation by addition of HCl and Na 2 CO 3 , as well as electroprecipitation, made it possible to extract more than 99 of silver in solution, being a primary novelty of this study.

Secondary sulfides those formed by supergene secondary enrichment are resistant refractory to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.
Supergene ores rich in sulfides may be concentrated using froth flotation. A typical concentrate
