Enhanced recovery methods for development of technogenic placers

Abstract

The article deals with the structure of gold mining and the prospects of the placer deposits development. The timeliness of the issue on the technogenic placer development has been justified. Their formation causes analysis has been made and the author has been performed the integrated estimation of remaining reserves in-place after the primary deposit development depending on the mining conditions of occurrence and the kind of valued component. The main methods of the enhanced recovery for the placer deposits reworking are offered. General difficulties of the technogenic placer reserves estimation by means of contemporary methods of geological exploration are presented. The author suggested the methods of indirect estimation considering the exploration results of unrecovered deposits and their exploitation during primary placer development. It has been observed that simplification and the speeding up of reserves estimation for technogenic placer makes it possible to enhance its development.
