EFFICIENCY RISE OF ACTION OF APOLAR FLOTATION REACTANTS (AFR) BY TREATMENT BY NATURAL ZEOLITES

The purposes are to study and to develop the new method of effiency rise of AFR action by their treatment by the natural zeolites, which provides the selectivity rise of cleaning of thin coal classes and the decrease of losses with the flotation tailings. The process criteria, which determine the optimum treatment regimes of AFR by the natural zeolites and the regeneration regimes of zeolites for the re-use, have been ascertained. The parrs of action mechanism of zeolites on the AFR have been determined. The determination technique of AFR reactivity at the coal flotation has been determined. The treatment process of AFR by the natural zeolites has been developed; the regeneration manner of exhausted zeolite has been offered; they allow to raise the rate of flotation process at the expense of selectivity rise of AFR action; the initial data for the request for the plant for the treatment of AFR by the zeolite have been produced. The determination teshnique of reactivity of AFR at the coal flotation has been developed. The activation manner of AFR has been tested under the industrial conditionsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
