Carbonaceous overburden rocks carry a heightened metallogenic potential. The possibility of extraction of valuable metals from 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 microelem...

The article describes studies of the process of mineral raw refinement in dry, wet form and with addition of chemical reagents. Specific energy spent to refinement has been determined in the course of disintegration, as well as specific surface of particles before and after refinement has been measured. The values of refinement of inter-phase surface area of disintegrated mineral particles and values of specific surface energy have been calculated. With the help of performed studies one may obtain quantitative exp...
