Formation of ore mass quality furing underground mining of different-type ore deposits

Purpose of the work: investigation of a possibility of separation of different-type ore mixtures formed in separate mining and determination of the dependence of the separation products yield and content of useful component in them in lump sorting and of the preconcentration of different-type ore mass and ore mixtures on the amount of the boundary contents of metals produced in dressing. The results of the work include the determination of the dependence of parameters of the ore type and ore mixtures lump separation process into types and grades on the amount of the boundary content of metals, use of this dependence for determining the rational value of the different-type mixture separation threshold with regard to the variation of its mass in the general ore flow, and development of a methodological approach and a methodology permitting design of technological schemes of formation of different-type ore quality and selection of rational options. Technological schemes are developed and parameters are substantiated for the new method of formation of the different-type ore qualityAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
