砷铋矿选矿工艺流程的研究是采用了比例为1:3.5的铋和砷的硫化矿矿样进行的。主要金属矿物是:磁黄铁矿、毒砂、黄铁矿、白铁矿、铋的硫化物及天然铋。非金属矿物为石英(70%)、方解石和绿泥石。毒砂多形成粒度大于20厘米的块状矿石,少量的浸染粒度是从0.01到3毫米。铋在共生集合体中呈硫化铋和自然铋的状态存在。多数的铋矿物单独地嵌布于石英中,其粒度为0.01—40毫米,主要介于0.5—1毫米之间。此外,它们常与磁黄铁矿共生,也有辉铋矿和毒砂的连生体。
Arsenic, bismuth ore beneficiation process research is the use of a ratio of 1: 3.5 of bismuth and arsenic sulfide ore samples carried out. The main metal minerals are: pyrrhotite, arsenopyrite, pyrite, white iron ore, bismuth sulfide and natural bismuth. Non-metallic minerals are quartz (70%), calcite and chlorite. Arsenopyrite mostly forms massive lumps with grain sizes greater than 20 cm with a small amount of dipped grains ranging from 0.01 to 3 mm. Bismuth exists in the state of bismuth sulfide and natural bismuth in the symbiotic aggregate. Most of the bismuth minerals are embedded in quartz alone, with a particle size of 0.01-40 mm, mainly between 0.5-1 mm. In addition, they are often symbiotic with pyrrhotite, and there are bionic bodies of bismuthinite and arsenopyrite.
