- W2376260042 abstract "In the paper, effects of the dosage of Na2S and sodium n-butyl xanthate on recovering copper and gold from the oxide ore containing Au and Cu (Cu 0. 83%, Au 0.97g/t) have been studied with the conventional sulfide flotation process. The effects of adding sodium alkyl hydroxamate to the system on the recovery of Cu and Au under the best consumption of Na2S and sodium n-butyl xanthate have also been studied. Experimental results show that the excessive dose of Na2S can depress copper and gold minera1s to a certainextent. However,by adding small amount of sodium alkyl hydroxamate, the unfavourable ef fect can be prevented and the recovery of Cu and Au can be increased obviously. In the small-scale test, the copper concentrate obtained is up to 17.68% Cu and 25. 07g/t Au in grade and the recovery of Cu and Au are 54. 30% and 62. 71 %, respectively. The recovery of Cu is increased by 12.60% and of gold by 16. 71% in comparison with the regime when sodium n-butyl xanthate is used alone as collector. Technical results from the commercial production are in line with those from the small-scale test." @default.
