CREATION OF LOCAL CIRCUITS IN WATER TREATMENT SYSTEMS FOR MOBILE ENRICHMENT COMPLEXES

Abstract

The design solution for the use of hardware method in the formation of water treatment system in the technological processes of metalliferous sands processing by mobile beneficiation complexes is considered. The purpose of the study is to develop a system for separation of process water from the flows of hydro-mixture from washing sands at alluvial deposits. From the comparative analysis and evaluation of known systems of recycled technological water preparation in the mining and processing industry the thin-layer separation effect is adopted. The object of the research is a thin-layer device, the novelty of which is protected by patents of the Russian Federation. The layout variant of this device made in the form of a module on the principles of nodes unification taking into account peculiarities of equipment operation in extreme conditions without additional expenditures of energy, with formation of technological flexibility and transportability at the change of washing places is shown. Industrial researches of thin-layer devices at the objects of alluvial metal-mining in water-treatment systems for sand washing have shown high dividing ability of the formed hydrosand mixture with possible return up to 80-90 % of technological water into turnover. A qualitative and quantitative assessment of the proposed hardware version of building closed circuits with the formation of local contours of water flows is given. Such a hardware design of the separation process of epheline tailings from sand washing out of contact with the natural environment increases the environmental safety of the surrounding area in mining areas and refers to the resource-saving technology
