THE USE OF THE BINDING PROPERTIES OF THE LIQUID TAILINGS AND ORES
Abstract
The relevance of reducing the cost of solid mixtures to fill technological voids in underground mining of ore deposits is due to the development of resource-saving and environmental trends in the mining industry.The aim of this work is to study the possibility of increasing the strength of the mixture by the use of liquid tailings multicomponent ores.In the course of laboratory and experimental - industrial experiment investigated the possibility of obtaining hardening stowing mixtures with the use of liquid tailings and ores.It is proved that the use of liquid waste processing processing significantly improves the strength and other technological properties of solid mixtures based on them is greater than the lower grade binder. Clarified the use of dam water as a sealer in the manufacture of solid mixtures for obtaining the same strength significantly reduces the consumption of cement, which is substantial economic effect. Dam water is used after the extraction of these metals, together with other associated commercial products reduces the cost of preparation of solid mixtures. Recommended method of extraction of the waste liquid metals under the influence of an electric field in diaphragm electrolyzers. It is shown that after extraction of the metals from pulpo-shaped waste, the latter represent a promising material for concrete production in the mining industry and construction industry.It is concluded that the use in the compositions of the solid mixtures, liquid waste hydrometallurgical processing significantly improves the strength and rheological properties of solid mixtures based on them due to salts of sodium sulfate, sodium chloride and surfactant water. Rational use of dam water increases the scope of progressive development systems with the bookmark hardening mixtures.
