S-稀丙基-s′-n-丁基三硫代碳酸盐和 s-苄基-s′-n-丁基三硫代碳酸盐特别适用于铜硫化物的浮选。其中,s-稀丙基s′-n-丁基三硫代碳酸盐尤其适合用作辉钼矿的浮选剂。例如:用稀丙脂戊黄药作捕收剂浮选1000克辉铜矿—辉钼矿原矿,加药量为0.01磅/吨矿石。平均回收率 Cu81.9%,Mo44.3%,Fe36.7%。用 s-稀丙基-s′-n-丁基三硫代碳酸盐代替稀丙脂戊黄药浮选1000克上述同种矿石,加药量与上相同。平均回收率 Cu S-allyl-s’-n-butyltrithiocarbonate and s-benzyl-s’-n-butyltrithiocarbonate are particularly suitable for the flotation of copper sulphides. Of these, s-dilute propyl s’-n-butyl trithiocarbonate is particularly suitable as a flotation agent for molybdenite. For example: the use of dilute propolis valerate as collector flotation of 1000 grams of chalcocite - molybdenite ore, dosing amount of 0.01 pounds / ton ore. The average recovery Cu81.9%, Mo44.3%, Fe36.7%. Using s-dilute propyl-s’-n-butyl trithiocarbonate instead of dilute propantheline drug flotation 1000 g of the same kind of ore, dosing amount and the same. Average recovery Cu
