ABSTRACT
Prospects of the application of new class of reagents - cloud point polymers with functional groups on the gold and platinum for extraction of micro- and nanoparticles of noble metals from fine grinded ores and by-products were considered. The reaction of synthesis of cloud point copolymer on the basis of N-isopropylacrylamide and N-acryloxysuccinimide, and its subsequent modification by groups of thioamine (TMPA), semicarbazide up (TMPB) and phosphine (TMPPh) were presented. Selective interaction of reagents TMPA, TMPB and TMPPh with noble metals and their prospective use as effective flocculants and reagents-collectors in flotation of refractory gold and platinum ores was revealed.
