Olijnyk T. Increase of selectivity of division of ores complex fluorspar by the basis of features minerals structure and reagents adsorption

The dissertation is dedicated to questions of development of technology of enrichment complex of ores of fluorspar of two deposits of Ukraine on the basis of an establishment of laws and dependences of selectivity of division of floatation of minerals from their structure and adsorption of superficial - active substances. In the work the basic parameters have determined which influence on the process of the floatation of the fluorspar, the quartz, the feldspar. The mechanism of action of tallactam, as collector at floatation of ores fluorspar complex is offered in the work for the first time. The model of floatation of quartz and feldspar on the basis of definition of energy maximum free and lowest engaged orbital is offered for the first time. Two variants of technology enrichment of ores are developed. The re-sults of researches in half-industrial conditions are confirmed . The basic results of work had found practical application in the development of the feasibility Report quality requirements on t o a deposit of Bahtin.
