绪言虽然早在廿世纪廿年代就发表了关于锡矿浮选的实验室研究资料,但只是近几年来才用于工业生产,应用该法选别锡矿石的主要技术困难并不在于锡石本身的浮选,因这种矿物用一般的捕收剂(包括黄药)在重金属离子活化的条件下是易于回收的;困难在于对与锡矿石共生的脉石矿物的抑制,其次是有时出现的消耗捕收剂的半胶质矿物的处理。关于玻利维亚的卡塔维(Catavi)选厂尾矿矿泥的锡石用硫代琥珀酰胺酸盐捕收剂浮选的 INTRODUCTION Although laboratory research data on tin flotation was published as early as the 1920s, it has only been used in industrial production in recent years. The main technical difficulty in using this method to separate tin ore is not that of cassiterite itself Because of the ease with which the minerals are recovered with common collectors, including xanthate, under the conditions of activation of heavy metal ions; the difficulty lies in the inhibition of gangue minerals symbiotic with the tin ores, followed by the occasional occurrence of Disposal of semi-colloidal minerals.
