氧化和还原过程是銅精炼的两个主要操作工序,这两个过程对精炼銅的最終质量起着重要的作用。 現在大多数的銅精炼厂,氧化过程已借向銅液中吹入空气或水蒸汽而被强化;而还原过程却一直沿用“插木还原”法。国内銅厂虽大都已采用木炭粉代替还原木,但插木操作仍未能完全取消,原木消耗較高。生产实践表明,使用木材或木材-木炭粉进行还 Oxidation and reduction processes are two major operations of copper refining, both of which play an important role in the final quality of refined copper. At most copper refineries, the oxidation process has been enhanced by the blowing of air or water vapor into the copper liquor, and the reduction process has been followed by the “insert reduction” method. Although most domestic copper mills have used charcoal powder instead of reducing wood, the operation of inserting wood has not been completely canceled and the consumption of logs has been high. Production practices have shown that using wood or wood - charcoal powder is still
