Experimental research on a oxide copper containing gold and silver in Xinjiang

The main useful element is copper,gold and silver.the malachite is main copper mineral,oxidation rate of copper is about 98%.The main existing state of gold are bare gold and half bare gold,the next is packing gold'.through test following index is obtain,for grade of gold,copper,silver being 48.15g/t,16.16%,114g/t,and of recovery of gold,copper,silver being 92.51%,74.23%,75.61%,on the condition of grade of gold,copper,silver being 5.6g/t,2.56%,17.72g/t in crude by gold-copper mixed flotation flowsheet and reasonable technology and medicament system.the leaching rate of copper is above 90% by leaching flotation gangue,the tall recovery of copper is above 97%.
