The problem of processing gold-carbon-containing ores with high sorption activity in the process of cyanidation makes it necessary to search for new and improve known methods of reducing the extraction of organic carbon into commercial products of enrichment. One of the most promising is the method of depression of carbonaceous matter in the process of flotation concentration, using various reagents depressors. This method allows you to extract gold and gold sulfides in the flotation concentrate leaving carbonaceous matter in the tailings. The effectiveness of the new reagent-depressor R-2, confirmed by flotation studies, with conducting semi-industrial and industrial tests on carbonaceous gold-bearing ores of various territorial formations. At present, the gold extraction complex for processing refractory carbon-containing ore with the use of reagent P-2 in the process of flotation enrichment is reaching its design capacity.
Taking into account the peculiarities of carbonaceous gold-bearing ores, which are characterized by a variety of forms of finding carbonaceous matter, causing their varying degrees of persistence to the cyanide process, it is of interest to study the nature of the effect of the above reagent on the surface of carbonaceous matter. This paper describes a possible mechanism for the interaction of the reagent-depressant R-2 with the surface of the carbonaceous matter, using various research methods. It has been established that the formation of the reagent-carbon-matter-water complex occurs because of physical sorption, by means of the Van-der-Waals interaction forces
