TECHNOGENIC MINERAL MATERIALS: COMPOSITION AND TECHNOLOGICAL PROPERTY FEATURES, GEOLOGICAL AND TECHNOLOGICAL MAPPING

Abstract

Issues of mineral composition study, technological properties in geological and technological mapping of minerals and its potential processing are considered. Technogenic sites of rare metals are analyzed and their location scheme within Russia is compiled. Study results are given for three potential sources of rare metal/rare earth commodities. They are stale tailings of Khingan tailings pond containing cassiterite, Batagay tailings pond rich in
Rb sands and gold plant tailings containing grey monazite. Based on study of mineral composition and technological properties of technogenic waste conclusion is made on its potential processing according to the unified flowsheet to produce salable concentrates if they belong to one technological type. Technogenic sites formed in processing ores of various technological types, where high spatial variability of technogenic sand quality takes place, require processing through different flowsheets.
