The basic design and technological approach to the creation of a local cycle of water circulation during the washing of metal-bearing sand at alluvial deposits of minerals is presented. The main element of the process is the principle of a polymineral hydraulic mixture separation in a stratified flow into a liquid and solid phase, embedded in a thin layer (channel) apparatus of a new generation. An analysis of the existing water circulation schemes during the washing of metal-bearing sands has been carried out, an assessment has been given, shortcomings have been identified, a new approach has been proposed to the system for providing water to mobile washing complexes with a positive environmental result based on the hardware design of the process. The possible flow patterns and the qualitative and quantitative characteristics of the proposed solutions in relation to existing washing complexes are shown. According to this purpose, a hardware circuit that includes a coarse stage of processing formed dredging tailings from enrichment of metal-bearing sands by washing them with the release of a large fraction of the class to -1 mm fine and the process of separation of the solid phase from the suspension to -0,001 mm are considered. The main principles and stages of development of ecologically pure technologies of water treatment based on the use of new constructive solutions are described, which are based on the process of thin-layer separation. Such an instrumental approach significantly reduces the contact of the mass flow of the slurry with the natural environment, forming a local system of water circulation of the process water. This takes into account the features of the mobile concentrating complexes operation, requiring flexibility of the technological process devices with a sharp reduction in the mass of the structure to the level of the mass of the concentrating complex with minimal energy consumption. Schematic diagrams on formation of local contours of a cycle of water treatment by the hardware method on the basis of unification methods use of the developed thin-layer devices in the form of modules are presented.
