The aggregate washing plant being fully operable while assembled and stored in the containers.
Abstract:
A method of mineral fuel beneficiation with subsequent delivery to the consumer by pipeline transportation relates fuel and energy complex and can find application in coal and slate energetics. Invention main objective is security of solid fuel delivery from mine (or an open cut coal mine) in already enriched form, with its subsequent through delivery to the consumer by pipeline on any distances in stream mode, without any intermediate transshipment operations. For this purpose use liquid with set complex physical, sanitary-and-hygienic and ecological properties, simultaneously, in 4 qualities: - As environment for grinding material that needed further reduction of size; - As separation environment for the subsequent, after reduction of size, deep underground gravitational enrichment of combustible mineral, - As motionless filler of the vertical pipeline, for buoyancy in it ready product from mine on terrestrial surface: - As carrying medium for final drift of end-product to the consumer by main pipeline. Depending on consumer type of solid fuel, a time of year, and weather conditions in which such, non-polluting, mining-energetic complex functions, there are used various technological approaches as to the general principles of construction of such, non-polluting, beneficiating- transport technological process as well as within the limits of separate links of such technological chain, various methods of the regeneration, used many functional liquids which are in the closed contour of circulation between producer of solid fuel and its consumer.
Abstract:
A method to process ilmenite-containing mineral material with high clay content includes processing involving settling velocity separation to prepare a first ilmenite concentrate followed by processing involving magnetic separation to prepare a second ilmenite concentrate. Settling velocity separation may include differential settling separation primarily for removal of clay and silica fines followed by elutriation for removal of coarse silica and additional fines. Also provided are high quality ilmenite concentrate products and slag products including low concentrations of problematic contaminant materials.
Abstract:
A sand sedimentation tank (10) is provided, the tank (10) comprises a tank body (11), an inlet (12) and an outlet (13), wherein the tank body (11) comprises side walls (14) and a bottom (15), the outlet is arranged in a side wall (11), and the bottom (15) has at least one raised part (16) and/or at least one recessed part (17). A sand separator is further provided, the separator comprises a grading unit (30), a particle collector unit (40), and the sand sedimentation tank (10) connected in series. A method for separating mixture of solid particles is further provided. The solid particles comprise first solid particles and second solid particles, wherein, the density of the first solid particles is lower than the density of the second solid particles; the method comprises: forcing the mixture of solid particles to flow with a solvent, making the second solid particles deposit in the flow process to form a layer (22) of the second solid particles, and forcing the first solid particles to continue flowing with the solvent, wherein, the density of the second solid particles is higher than the density of the solvent.
Abstract:
A method and apparatus for reblending sand whereby multiple reblending tanks with a plurality of reblending stations have thin respective outputs joined through a single control system.
Abstract:
A method and system for recovering diamonds (45) from diamond bearing material sich as kimberlite ore or sea shells, comprises the steps of subjecting the material to a contactless disintegration stage (26). By convecting electrical energy into a pressure pulse (33) in an energy converter (34.1), the propagating pressure pulse (33) causes the material to disintegrate into particles (47) smaller than the diamonds. The particles and diamonds are then separated by known techniques.
