丘提奇(Cutech)工艺是一种从氰化物溶液中回收金的新湿法冶金工艺,主要优点是:回收的金量大,呈金属状态可直接冶炼;氰化物能经济回收和循环使用;同时回收金属铜。矿石中的铜和金用氰化物溶解,然后,在非常精确的控制条件下,用药剂处理浸出阶段的澄清富液。这样就能沉淀出金和铜,并使氰 The Cutech process, a new hydrometallurgical process for the recovery of gold from cyanide solutions, has the following main advantages: large amounts of gold are recovered and can be directly smelted in metallic form; cyanide can be economically recovered and reused; At the same time recovery of metallic copper. The copper and gold in the ore are dissolved with cyanide and then the clarified rich liquid in the leaching stage is treated with the agent under very precise control conditions. This will precipitate gold and copper, and make cyanide
