混合甲苯胂酸是一种具有较好选择性能的捕收剂,可用于锡石、黑钨、白钨细泥的浮选,又可分选稀有、稀土和氧化铅等矿物,效果良好。我所自1961年开始进行甲苯胂酸的合成与浮选锡石的研究,在十多年的实验室研究工作中,改进了甲苯胂酸的合成步骤,进行了混合甲苯胂酸的扩大试验,已由株洲选矿药剂厂建厂生产。混合甲苯胂酸的使用法也有新的发展,一些厂矿按照自己矿石的特性,灵活配制使用,有的厂矿将混合甲苯胂酸与煤油、油酸合用;有的与油酸乳化剂合用;有的与氧化石腊皂合用,与烷基磺酸钠合用,甚至与黄药合用以找出适合自己矿石性质的药剂制度,大大发展了混合用药的优越性,强化了分选,节约了混合甲苯胂酸的用量,降低了选矿成本。
Toluenesulfonic acid is a kind of collector with good selectivity. It can be used for flotation of cassiterite, black tungsten and white tungsten fine mud, and can also be used for sorting rare earth, rare earth and lead oxide minerals and has a good effect. Since 1961, I started the research on the synthesis and flotation of toluene arsonate. In the more than ten years of laboratory research, the synthesis of toluene arsonic acid has been improved and the extended test of mixed toluene arsulfuric acid has been carried out. Zhuzhou beneficiation pharmaceutical factory has been built plant production. There is also a new development in the use of mixed toluene arsulfuric acid. Some mines are formulated flexibly according to the characteristics of their own ores. Some factories and mines will mix toluene acid with kerosene and oleic acid, some with oleic acid emulsifiers, and some Combined with the oxidation of paraffin wax soap, sodium alkyl sulfonate and even used in combination with the xanthate to find suitable for their own nature of the pharmaceutical agent system, greatly enhanced the advantages of mixed drugs, and strengthen the sorting, saving mixed toluene arsine The amount of acid, reducing the dressing costs.
