苏联某锑—砷矿石的选矿没有得到纯锑精矿,因为在选锑的同时砷化合物也浮起来了。锑精矿中的高含量砷(4—8％)使金属锑的制取复杂化。在工业条件下,这种精矿用火法或湿法均可处理。
The antimony-arsenic ore beneficiation in the Soviet Union did not result in pure antimony concentrates because the arsenic compound floated in the presence of antimony. The high content of arsenic (4-8%) in antimony concentrates complicates the preparation of metallic antimony. In industrial conditions, this concentrate can be treated by fire or wet method.
