本文介绍了以不用硫酸铜为目的而创制的新药剂浮选铁闪锌矿(硫化锌)的试验室研究结果。选择了环硫化物作为这种药剂的基础,因为它们对锌和镉具有特殊的亲和力。试验了增加其可溶性和往环硫化物中引入无机和有机酸、氨、酚、苯胺、二乙胺、吡啶等各种基团。其中以环硫化物与胺结合的这一组药剂,一般对硫化锌的浮选有不同程度的效果,而以硫乙烯与苯胺的结合产品所得的结果为最佳,虽然据说苯胺基乙基硫醇是苯胺与硫乙烯的反应产品,但已得出结论;硫乙烯-苯胺结合产品对硫化锌浮选之所以有效并不完全是由于生成了硫醇。文章中对应用硫乙烯-苯胺药剂的经济价值也进行了讨论。 This article presents the results of a laboratory study of a new pharmaceutical agent, flotated sphalerite (zinc sulphide), that was created without the use of copper sulphate. Ephedrides were chosen as the basis for this agent because of their special affinity for zinc and cadmium. Experiments have been conducted to increase its solubility and introduce various groups of inorganic and organic acids, ammonia, phenol, aniline, diethylamine, pyridine and the like into the cyclic sulfide. Among them, the combination of epithio sulfide and amine is generally effective on the flotation of zinc sulfide to some extent, and the result obtained from the combination of sulfur and aniline is the best, although aniline ethyl sulfide Alcohol is the reaction product of aniline and sulfur ethylene but it has been concluded that the effect of the sulfur-ethylene-aniline combination on the flotation of zinc sulfide is not entirely due to the formation of mercaptans. The article also discusses the economic value of using thioethylene-aniline pharmaceuticals.
