Novel polymeric sulfide mineral depressants |
| abstract |
Novel depressants for depressing sulfide minerals during froth flotation of ores to recover value minerals are disclosed, as well as a method for their use in the froth flotation. The novel depressants are terpolymers of a (meth)acrylamide, an allyl thiourea and a hydroxyalkyl (meth)acrylate. |
