  • Response of low grade gold ore to cyanidation and thiourea

    Jun 23, 20170183;32;ABSTRACTIn this study, leaching tests were conducted on representative samples provided from Hamze Qarnein gold deposit with grade of 0.8 ppm using cyanidation and thiourea leaching. Effective parameters including particle size, reagent concentration, oxidant concentration, pH, and dissolution time were examined in both cyanidation and acidic extraction with thiourea.
