摘要
研究了广西某选厂低品位锑铅锌多金属硫化矿脉石中的炭质成分,查明金属回收率低的主要原因是预先脱炭作业而使金属损失,证明不可能采用机械方法除炭在于炭质与脉石矿物共生关系复杂,并试验出新的分选工艺,使产品质量和金属回收率显著提高.
Carbonaceous material in the low grade multi-metal Sb-Pb-Zn sulphide ore from the mineral processing mill in Guangxi has been examined. It is showed that the metal loss in the product is mainly caused by decarbonization processing beforehand, and that the complex intergrowth between the carbonaceous material and gangue minerals makes decarbonizing machanically impossible. A new processing method or technological process has been tested which improves the quality of products and raises the recovery of metals.
