1. 火法:

1. fire method:

通过熔融冶炼和电解精火炼生产出阴极铜,也即电解铜,一般适于高品位的硫化铜矿。

Cathode copper, also known as electrolytic copper, is produced by smelting and electrorefining, which is generally suitable for high-grade copper sulfide.

除了铜精矿之外,废铜做为精炼铜的主要原料之一,包括旧废铜和新废铜,旧废铜来自旧设备和旧机器,废弃的楼房和地下管道；新废铜来自加工厂弃掉的铜屑(铜材的产出比为50%左右),一般废铜供应较稳定,废铜可以分为：裸杂铜:品位在90%以上；黄杂铜(电线):含铜物料(旧马达、电路板)；由废铜和其他类似材料生产出的铜,也称为再生铜。

In addition to copper concentrate, scrap copper is one of the main raw materials for refining copper, including old scrap copper and new scrap copper. The old scrap copper comes from old equipment and old machines, abandoned buildings and underground pipelines. The new scrap copper comes from scrap copper (the output ratio of copper is about 50%), and the supply of scrap copper is generally stable, Scrap copper can be divided into: bare miscellaneous copper: grade above 90%; yellow miscellaneous copper (wire): copper containing materials (old motor, circuit board); copper produced by scrap copper and other similar materials, also known as recycled copper.

2.湿法:

2. wet method:

一船适于低品位的氧化铜,生产出的精铜称为电积铜。

A ship is suitable for low-grade copper oxide. The refined copper produced is called electrodeposited copper.
