At gold mining in the 19th～20th centuries on technogenous deposits of cryolitozone, considerable amounts of mercury-containing elements (amalgams) have been accumulated. Urgency of their utilization is caused by necessity of providing safe vital activity. It can be achieved when elaborating up-todate technologies providing self-support of utilization as a consequence of extracting precious metals. Difficulty of this problem realization is caused by the absence of theoretical and applied elaborations of making the appropriate works in cryolitozone. The main trends of the problem solving on the grounds of creating scientific method foundations for investigating the cryolitozone amalgams transformation have been considered in the paper. Dynamics has been shown and the revealed regularities of their transformation,testifying of the occurrence of hydrometallurgic processes in cryolitozone massifs in situ, resulted in the decline of gold reserves at decreasing dispersity and increasing hallmarking, have been analyzed.
