MINING THE GOLD BY METHODS OF GEOTECHNOLOGY. PART 2. PRACTICAL EXPERIENCE IN HEAP AND UNDERGROUND LEACHING OF GOLD

Abstract

Review of international practical experience in mining the gold by methods of heap and underground leaching has been presented. Brief characteristics of production processes at particular enterprises have been considered. Potentialities of geotechnology under conditions of negative temperatures have been discussed. New prospects for geological mining of metal mining by method of leaching at negative temperatures have been described. In this case, geotechnological process can maximally be closed to natural chemical weathering. The geotechnological process can be carried out with minimal participation of people.
