Technogenic drains as an source of titanium- zirconium raw materials

Abstract

The paper under rewiew deals with an actual modern problem of development of tailings processing of sands. The material characteristics of the tailings of the enrichment of a number of existing enterprises of the Central region of Russia are given. The latest data from the well-known largest Centralnoe deposit, where in 2012–2014 work was carried out (with the participation of the authors) to increase its investment attractiveness, was used as a benchmark for comparison. It is shown that the concentrate of enrichment tailings is not fundamentally different from the concentrate of the reference object neither in mineralogical composition nor in its quality, and the volumes of its possible associated extraction are such that they can largely cover the deficit existing in the country for titanium-zirconium raw materials. At the same time, many environmental and legal problems simply do not arise, natural resources are protected, and the regional economy acquires new growth points.
