Development of Methods of Determination and Recovery of Strategic Metals from Overburden Rocks in Coal Beds
https://doi.org/10.18412/1816-0395-2016-5-16-21
Abstract
The study covers the possibilities of analysis of overburden rocks in the south of the Far East - a new alternative source of strategic metals - by plasma spectrometry. A rational sample preparation procedure based on melting samples with lithium metaborate was used to define macro and trace elements (from major up to Be, Sc, V, Cr, Co, Ni, Cu, Zn, Ga, As, Rb, Sr, Y, Zr, Nb, Mo, Cd, Sn, Cs, Ba, Hf, Ta, W, Pb, Th, U and rare earths) from one weighed portion. The concentration of noble metals was defined by the neutron activation analysis. The distribution of commercial elements at various stages of overburden rock processing was studied. The development of new analytical and beneficiation methods allows to outline solutions for the issue of developing a technology of extraction of commercial elements from overburden rocks in coal beds.
