POLYMER AND METHOD THAT INCLUDES THE TREATMENT OF VALUABLE MINERALS FROM MINES WITH SELECTIVE REJECTION OF BARGAIN AND OTHER VALUABLE MINERALS USING SUCH A POLYMER |
| abstract |
Depressants to depress sulfur minerals during ore foam flotation to recover valuable minerals, as well as a method for use in foam flotation. Depressants are terpolymers of a (meth) acrylamide, an allyl thiourea and a hydroxyalkyl methacrylate. Said terpolymers comprise recurring units of formula (I). |
