Oliynyk T. The development of sciences bases of complex technology dressing of titanium-phosphorous ores of native deposits of Ukraine.

The dissertation is devoted to of science bases of complex technology dressing titanium-phosphorous ores beneficiation of native deposits of Ukraine, organic compounds from aqueous solutions on mineral surface specific adsorption regularities investigation, theoretical and experimental grounding of correlations between adsorption and electron substance properties. It is proved that efficiency of enriching of ore with aggregate dissemination of minerals is determined selectivity and degree of opening of every mineral which predetermines possibility of concentration of separate minerals in the proper factions on the stage of preparation ores of fine wheat flours to enriching and increase of efficiency of separation of every faction for the receipt of the proper concentrates. The idea of selective division of polyminerals ores of native deposits is realized in the construction of multifood magnetic a separator with the magnetic system, which consists of a few sections with induction of the field which ismultiplied, after motion of motion of product which is enriched. It is determined that floatation selectivity is defined by polar organic compounds adsorption caused by manifistation of weak chemical interactions with an adsorbent and water molecules. It is suggested for the first time and grounded experimentally to consider the specific adsorption in approximate adsorption models controlled by adsorbate atom effective charge values, by water and adsorbent surface.
