金川现行精炼流程,除1980年实现的合金直接处理提取贵金属新工艺外,自60年代投产以来,镍铜主流程一直沿用至今,生产了大量的镍和贵金属,成为我国镍和铂族金属最大生产基地。但由于它是起步于我国镍工业的创业期,自然就不可能是很完善的。因此,在经过这么长时间的生产实践之后,我们在从讨论它的得失中提出改进的办法,显然是必要的。 Jinchuan current refining process, in addition to the alloy obtained in 1980, the new direct processing of precious metals extraction process, since the 60’s put into operation, the main process of nickel and copper has been in use so far, producing a large number of nickel and precious metals, as China’s largest production of nickel and platinum group metals base. However, since it was started in the nickel industry in our country, it naturally can not be perfect. Therefore, after such a long period of production practice, it is obviously necessary that we propose improvements from the discussion of its pros and cons.
