酸溶法从铁基硬质合金中回收金属材料

Retrieving Metal Materials by Means of Disused Hard Iron-bounded Alloy

探讨了用无机酸处理废铁基硬质合金的方法,介绍了焙烧、浸取、水解、结晶和还原等过程参数,提出了分离合金组元、制取金属材料与化学试剂的原理和生产工艺。

This paper reports the production principle and technology of metals material using the disused hard iron -bounded alloy as materials, using the method of inorganic acid dissolving processing and combining to roast, precipitate, crystallize, reduce etc.
