羊拉铜矿选矿技术难题及进展

Problems and Development of Mineral Processing Technology in Yangla Copper Deposit

本文以羊拉铜矿作为研究对象,通过对其工艺矿物学研究发现,羊拉铜矿由于经过多次中、低温热液叠加成矿作用,矿物成份较为复杂,铜矿物的嵌布粒度不均匀,并且氧化率高,导致选别难度极大。综合相关文献,从浮选工艺流程、浮选药剂、浮选设备、酸浸、微生物浸出等方面对羊拉难选铜矿石进行了综述。

This paper took the Yangla Copper Deposit as the research object, and through the research on the process mineralogy,found that due to the mineralization of many times of superposition of mid-low temperature hydrothermal solution, mineral composition was complex, copper mineral particle size distribution was not uniform, and the oxidation rate was high, resulting in separation difficult.According to related literature, from flotation process, flotation reagent, flotation equipment, acid leaching, microbial leaching and other aspects, the Yangla refractory copper ores are reviewed.
