Abstract:
In the paper, the author generalizes the material on manifestations of alunites in the Amur region. Burindinsky and Dulneysky manifestations are estimated by the author in more detail from the point of view of possible gold mineralization of secondary quartzites. However, volcanogenic formations of the Taldinsky complex, genetically linked with manifestations of alunites, have a wide area development. That means it is possible to identify industrial facilities of alunite ores. In order to determine the geological and economic model of a possible industrial alunite deposit in the geographical and economic conditions of the Skovorodinsky district in the Amur region, the author made technical – economic calculations. The calculations take into account a complex processing of raw materials of allunite and synnyrite in the waste-free production of alumina, sulfuric acid and potassium sulfate, vanadium oxide, as well as the processing of residues for the production of cement and other building materials. Technical and economic calculations of the industrial fi eld model (on the example of the Burindinsky manifestation) show that in the Skovorodinsky district of the Amur region the development of the fi eld can be profi table if the resources are more than 300 million tons of alunite ores with an average alunite content of at least 34%, and alumina – 12,5%. In modern conditions, these conclusions need to be revised, but without diminish-ing the practical importance of alunites as complex and waste-free raw materials for alumina, coagulants, chlorine-free potassium fertilizer and other industrial products.
