Today the reagents used in the beneficiation of polymetallic gold-bearing ores of Novo-Shirokinsk deposit, are not effective. This causes the loss of valuable component in the final tailings. The relevance of this work lies in finding the most effective modes of combining new and commonly used reagents in the technological scheme of enrichment of gold-bearing lead-zinc ores. The article presents the results of the laboratory studies on the development of effective technologies of flotation concentration of complex polymetallic lead-zinc ores of Novo-Shirokinsk deposit. The article shows the possibility of replacing the traditional reagents used for the current concentrator, sulfhydryl reagents-collectors of the type aeroflot sodium butyl and sodium aeroflot-isooctylphenyl that were not previously used in the technological scheme of ores processing of Novo-Shirokinsk deposit.
Complex polymetallic ores in which valuable components are minerals of lead, zinc, copper, noble metals, are very complex and referred to hardly enriched objects for mineral processing. Additional extraction of noble metals largely determines the cost of the mineral raw materials’ processing.
The widely used flotation method of mineral processing is based on the use of chemical reagents, which are primarily used in the transfer of valuable components in the concentrate.
The efficiency of polymetallic ores enrichment primarily depends on the kind of reagents used and accepted operating parameters to obtain high-quality concentrates of non-ferrous metals at the lowest possible technological losses of metals, valuable components in tailings.
In practice in flotation of non-ferrous metals ores xanthate (butyl, ethyl, isopropyl), aeroflot (dithiophos- phates), dithiocarbamates, mercaptans have traditionally been used as. In the flotation of sulphide and oxidized ores, some of these reagents can be used in individual form or in combinations with other types of reagents.
The article analyzes the results of laboratory studies of flotation enrichment of lead-zinc gold-containing ores of Novo-Shirokinsk deposit. In the laboratory the experiments were conducted, using two varieties of sulfhydryl reagents-collectors of the type aeroflot sodium butyl and sodium aeroflot-isooctylphenyl that were not previously used in the technological scheme of Novo-Shirokinsk deposit. The prospect of their use in flotation of polymetallic lead-zinc ores in the feasible technological scheme at Novo-Shirokinsk deposit is suggested. The most effective modes of combining new and commonly used reagents in the technological scheme of enrichment of gold-bearing lead-zinc ores are described. The need for further areas of the research to identify effective modal parameters of new individual reagents in a laboratory test, as well as their various combinations is proved |
