Embodiment 1
[0021] An ore dressing agent for separating and recovering precious metals from copper anode slime, comprising 3 parts by weight of a collector, 10 parts by weight of an inhibitor and 10 parts by weight of a foaming agent, wherein the collector is pinitol Xanthate and pinitol black medicine, the molar ratio of pinitol xanthate and pinitol black medicine is 2:1, the inhibitor is sodium hexametaphosphate, and the foaming agent is pinitol oil.
[0022] The preparation method of the pinitol xanthate is as follows: massaging pinitol oil: sodium hydroxide: carbon disulfide=1:1:1.2, reacting at 15° C. for 3 hours to obtain pinitol xanthate.
[0023] The preparation method of the pinitol black medicine is as follows: according to the molar ratio of pinitol oil: phosphorus pentasulfide: sodium hydroxide = 4:1:2, react at 80° C. for 1 hour to obtain the pinitol black medicine.
[0024] The method for separating and recovering precious metals from copper anode slime by using the above-me...
