摘要
新疆某金铜矿主要回收元素为金和铜,并伴生回收银。铜以孔雀石为主,氧化率为98%。金以裸露和半裸露金为主,占57.41%,其次为包裹金。经浮选及浸出流程试验及条件试验研究,采用金铜混合浮选流程及适宜工艺条件、药剂制度,在原矿含铜2.56%含金5.6g/t的条件下,获得混合精矿金、铜和银品位分别为48.15g/t、16.16%、114g/t,金、铜,银的回收率分别为92.51%、74.23%、75.61%的指标。浮选尾矿进行酸浸,铜浸出率达90%以上,铜总回收率97%以上。
The main usetul element is copper, gold and silver, the malachite is mare copper mineral, oxidation rate of copper is ahout 98 %. The main existing state of gold are hare 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%.
