Rate raising of flotation of tungsten-containing ores with application of organic dispersants

There the study purpose is to rise the flotation efficiency of tungsten-containing ores on the basis of reactant regime improvement by way of alkine use as the activity regulators and as the selectivity regulators of action of oxihydryl collectors. The dispersing activity of some alkines with respect to the natrium oleate, which brings on the decrease of its micella-formation in the ageous solutions, has been determined. It is presented that the alkine presence has an effect on the given solutions, which is analogous to the temperature rise by 40-50 degrees that causes the flotation activity of natrium oleate. The form change of collector sorption on the minerals in the alkine presence has been proved; it improves the selection of minerals. The effective reactant regimes of flotation of different types of tungsten ores, which allow to rise the process variables and to produce the scheelite concentrate of more high mark, have been developed. The range of reactants-dispersants has been extended. The study results have been recommended for the introduction at the beneficiating factory of Lermontov Ore AdministrationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
