DEPORTMENT OF COPPER, SILVER, BISMUTH AND SELENIUM DURING SOLVENT EXTRACTION OF GOLD

DEPORTMENT OF COPPER, SILVER, BISMUTH AND SELENIUM DURING SOLVENT EXTRACTION OF GOLD,  maj 2011 r. : Solvent extraction technology is a technology that is used comercially for gold recovery and purification from copper electrorefining anode slimes.       The recovery of gold and the deportment of selected impurities were investigated during the solvent extraction of commercial aqueous leachate with dibutyl carbitol (DBC).       The results obtained were analyzed in terms of gold extraction and deportment of selected impurities, such as copper, silver, bismuth and selenium. This project demonstrated gives a study of batch, continuous as well as mini pilot plant to understand the capability of a continuous solvent extraction system to produce a lower gold bearing raffinate in both loading and washing.       The deportment of impurities during all the experiments was also compared.
