二、矿石预处理后浸出的方法(一)铜精矿焙烧—浸出—电解(置换)法(RLE 法) 硫化铜精矿经焙烧后浸出,是湿法提铜历史最悠久而应用最广的方法之一,但其局限性是众所周知的。例如铜回收率较低,贵金属损失在浸出渣中,相当大量的过剩废电解液需要处理,而未充分利用。故在国外多用于硫化铜矿和氧化铜矿的联合处理,或用于处理 Cu-Zn,Cu-Ni,Cu-Co,
Second, the ore pretreatment leaching method (a) of copper concentrate roasting - leaching - Electrolysis (replacement) method (RLE method) copper sulfide concentrate leaching after roasting, is the history of copper extraction the oldest and most widely used One of the ways, but its limitations are well known. For example, copper recovery rate is low, precious metal loss in leaching residue, a considerable amount of excess waste electrolyte needs to be handled, but not fully utilized. Therefore, it is widely used abroad for copper sulphide ore and copper oxide co-treatment, or for the treatment of Cu-Zn, Cu-Ni, Cu-Co,
