Abstract: | The test data on sorption and flotation properties of reagent-collectors: dithiophosphate (DTP) and mercaptanbenzothiazol
(MBT) relative to Pt-Cu-Ni minerals (chalcopyrite, pentlandite, and pyrrhotite) are presented. It was established by UV-spectroscopy
analysis that MBT sorption on the study mineral specimens amounted to 62 % for chalcopyrite, and 15–30 % for pyrrhotites,
88 % for pentlanditepyrrhotite specimen to the initial reagent quantity. Adsorption of isopropyl and isobutyldithiophosphate
on pentlandite-pyrrhotite was 59% and 82 %, respectively, along with none actual adsorption of these reagents on pyrrhotite..
It is shown that the selective sorption of MBT and DTP proves the expediency of applying the above complex-forming reagent
mixture as selective collectors for platinum-bearing sulfide minerals at Pt-Cu-Ni ore flotation.
