Abstract:
A problem of complex mineral resources development is urgent and priority, it is aimed at the realization of the processes of their ecologically safe development, one of its components is revealing the influence of the forms of element compounds in raw materials and in the processing products. In view of depletion of the strategic reserves of traditional metal, unconventional sources of minerals are beginning to play a leading role. Carbonaceous overburden rocks carry a heightened metallogenic potential. The possibility of extraction of valuable metals from graphitic shales, natural bitumens and overburden rocks of oil fields is considered. The results of mineralogical and technological researches of samples are presented. The analysis of sample has shown an increased content of valuable microelements in some objects. All samples contain carbon of varying degrees of metamorphism. The fact of simultaneous concentration of carbonaceous rocks by several microelements is known, the combination of them under another conditions is considerably different from chemical properties. Depending on the type of raw material, research is carried out in three directions: stadial diagnostic sorption leaching, flotation concentration, magnetic concentration and extraction. The research of the scattered carbonaceous substance from the objects of research suggests that the asphaltene fraction of bitumenoids are concentrators of metals. Research has shown the prospects of inclusion of unconventional carbonaceous raw materials for the extraction of valuable metals.
