一、前言为了增加硫化矿捕收剂的产量及品种,以滿足工业需要,国內外做了許多研究。在新型黄药方面,烷基芳基黃药在文献中早有介紹,最近在法国发表一項新型黄药的专利。列雅曾研究用氧乙烯醇合成的黄药。我国冶金选矿剂工厂曾研究苄黄药,认为可以代替丁黄药,但不如戊黃药。除黄药外,比較成功的硫化矿捕收剂有巰基苯駢噻唑,在美国列为400号浮选剂。塔加尔持、瓦克、保格丹諾夫及雷布金娜等人曾研究該药剂,认为是硫化矿的捕收剂,并可浮选白鉛矿、孔雀石
I. Preface In order to increase the yield and variety of sulfide ore collector to meet the industrial needs, many studies have been done at home and abroad. In the field of novel xanthate, alkylaryl xanthate has been introduced in the literature, recently a patent for a new type of xanthate has been published in France. Liya has studied the synthesis of xanthine with oxyethylene alcohol. China’s metallurgical mineral processing plant has been studying benzyl xanthate, that can replace butyl xanthate, but not as good as valerate. In addition to xanthate, the more successful sulphide collectors are mercaptobenzothiazole, which is listed as No. 400 flotation agent in the United States. Taggart, Wacker, Bogdanov and Rybinkina who have studied the agent, that sulfide ore collector and flotation of lead, malachite
