本发明介绍在介质pH值低于8.8的贫镍细磨蛇纹石矿浆中,用少量硫化钠和硫酸铜,以及戊基黄原酸钾、松油、煤焦油、杂酚油、蓝色樟脑油和塞卡弗罗特(系日本氰化工业所出产的一种捕收剂)等药剂浮选镍的方法。采用此法很容易把镍的硫化物和硅酸盐等浮游富集。由于蛇纹岩中呈硫化物和硅酸盐状态存在的镍化合物含量很低,而且又呈微粒嵌布,因此,用一般的浮选方法,很难富集。使用过去 The present invention describes the use of small amounts of sodium sulfide and copper sulfate, as well as potassium pentylxanthate, pine oil, coal tar, creosote, blue camphor And sekaflorate (a collector made by Japan Cyanuric Industry), and the like. Using this method is easy nickel sulfide and silicate and other floating enrichment. Because of the low content of nickel compounds present in the sulphide and silicate states and the intrusion of fine particles, it is very difficult to enrich by conventional flotation methods.
