硫醇用于选矿早在60年代就有人作硫化矿石的捕收剂,但低级硫醇奇臭,空气中含5×10~(-8)的乙基硫醇后,人们便可以嗅到其臭味,加之硫醇制造成本高,不如黄药制造方便,这就大大妨碍了这种药剂在选矿领域中的应用。近二年来,由于上述问题的解决,硫醇再次引起人们的注意。 Thiol used for beneficiation As early as the 60s some people as sulfide ore collector, but the low-grade mercaptan stinks, the air containing 5 × 10 -8 (-8) of ethyl mercaptan, people can smell it Odor, combined with the high cost of mercaptans, is not as convenient as the manufacture of xanthate, which greatly hinders the application of this agent in the field of mineral processing. In the past two years, due to the solution of the above problems, mercaptans again attracted people’s attention.
