Patent and information analysis of evaluating the development level of technical solutions for gold heap leaching from technogenic raw materials in the cryolithzone

Abstract

An analysis of the development level of physical and chemical gold heap leaching geotechnology, used by leading gold mining countries, has been carried out with the use of the patent-information analyses of technical solutions. Based on the use of the existing information, a comparative quantitative evaluation of technical solutions for the objects of the invention at two modes of leaching (seasonal and year-round) is given.
