| Abstract: | A copper-gold ore is characterized with copper grade of 0.72%,copper oxidation rate of 31.94%,gold content of 3.45g/t containing large amount of mud,belonging to refractory ore.Several tests were conducted to find out the impacts of a variety of oxide copper ore collectors and gold-silver synergists on the flotation.Good indicators have been achieved with copper grade of 23.21%,recovery rate of 89.91%,copper concentrates containing gold 108.04g/t,silver 750.68g/t,and gold and silver recovery rates of 87.37%,92.99%. |
