硫氮九号是北京矿冶研究院1964年试制成功的一种新型捕收剂。某些厂矿在推广使用硫氮九号选别硫化铅矿物中都取得了较好的效果。我矿在选别某复杂多金属矿石的半工业试验中,曾试用硫氮九号选别硫化铋矿物,取得了显著的效果;提高了铋的回收率,降低了药剂消耗,尤其是大幅度地降低了抑制剂(氰化钠和硫酸锌)的用量,改善
Sulfur nitrogen on the 9th Beijing Institute of Mining and Metallurgy in 1964 a successful trial of a new collector. Some factories and mines in promoting the use of sulfur nitrogen No. 9 lead sulfide minerals have achieved good results. In the semi-industrial test of selecting a certain complex polymetallic ore, the mine has tried to select the bismuth sulfide bismuth sulfide with sulfur nitrogen No. 9 and achieved notable results. The recovery rate of bismuth is increased and the consumption of medicaments is reduced. In particular, Reduce the amount of inhibitors (sodium cyanide and zinc sulfate), improve
