THE CONCEPT OFFORMING, OPERATING AND RECULTIVATION OF LARGE SCALE MULTITIER STACKS IN GOLD HEAP LEACHING IN ARID CLIMATE

摘要

It is recommended to process a stack with cyan-containing solution step-by-step, to divide a stack preliminary in several parts differing with conditions of their irrigation during heap leaching in the conditions of negative water balance. Fresh (additional) water is forwarded to the part of a stack which is already worked. This approach allows to decrease amount of additional fresh water, tolower volumeof goldbearing solution in pore channels of ore mass.
