钨钼铋多金属矿石选矿技术资料

Release date:2017-10-14  Browse times:1401

属矿石选矿 (processing of complex ore containing tungsten,molybdenum and bismuIth)

从含钨钼铋多金属矿石中分离并富集钨矿物、钼矿物和铋矿物的过程。选矿产品有钨精矿、钼精矿和铋精矿等。钨钼铋多金属矿是中国著名矿产。主要分布于湖南省郴州地区,其柿竹园矿区是一特大型矿床。矿石中主要工业矿物为白钨矿、黑钨矿、辉钼矿、辉铋矿、石、萤石、黄矿等。(见表)虽然矿石中有用成分多,但

以回收白钨矿为主,选矿工艺流程多采用以浮选法回收白钨矿的浮选一重选一磁选一浮选或重选一浮选一磁选一浮选联合工艺流程综合回收白钨矿、黑钨矿、辉钼矿、辉铋矿等。使用的浮选药剂有碳酸钠、水玻璃、氧化石蜡皂、2号油、硫氮9号、硫化钠、石灰、氢氧化钠等。矿’石经三段一闭路破碎流程破碎后给入磨机。磨矿细度85%一200目。先浮选钼铋得混合精矿,然后钼铋分离浮选得钼精矿和铋精矿。钼铋浮选尾矿进行铋硫浮选,所得泡沫产品再分离浮选得铋精矿与铋中矿。铋硫浮选尾矿浮选白钨矿,所得泡沫产品加温精选得白钨精矿,精选尾矿用摇床回收得黑钨精矿。1992年入选矿石品位为:WO30.6%;Mo0.12%;Bi0.19%。生产指标为:钼精矿含Mo 48.6%,浸出效率86.29%;铋精矿含Bi 46.59%,实际回收率63.22%;钨精矿含WO366.83%,实际回收率58.66%。
