VARIATION OF THE PROPERTIES OF NON-FERROUS MINERALS IN TECHNOGENETIC DEPOSITS

摘要

Considerations of ecologically clean development of mineral resources has led researchers to see the need for general development of technogenetic deposits, i.e., deposits of minerals resources generated as wastes from metallurgical production [1-3]. According to rough estimates, the total value of useful components contained in sulfide-bearing technogenetic ore is comparable with the resources of mineral ore buried underground [4]. Thus, it is important to create a description of the technological properties of minerals present in technogenetic deposits, the kinetic laws which describe how these properties vary, in particular, the variation of the surface properties of minerals under the influence of hypergenetic processes occurring in dumps and tailing pits, and also establish which mineral phases are represented in new formations.On the other hand, oxidizing sulfide minerals present in stored tailings may serve as a source of uncontrolled pollution of the environment with heavy metals (Cu, Ni, Co, Pb, Zn, Bi, Sb, As, etc.) [5, 6]. Hence, the study of the processes which occur when sulphide-containing technogenetic material is stored is of undoubted interest, particularly from the standpoint of ecology.
