SLUICE BOX-FREE METHOD OF BENEFICIATION OF SANDS OF MAN-MADE PLACER DEPOSITS OF NOBLE METALS

摘要

enrichment of mineral resources, technology of processing of gold-carrying sands of man-made deposits. SUBSTANCE: sluice box-free method of beneficiation of sands of man-made placer deposits of noble metals includes process of removal of boulders with use of proper gear, process of trapping of fine and thin gold, process of storage of dewatered crushed gold ore, of uninterrupted direction of collected clarified water for water recycling. Process of classification in hydraulic screen irregularly vibrating in bin with water is conducted before process of trapping of fine and thin gold. This process of trapping of fine and thin gold as well as collection of clarified water are carried out in spiral-laminated concentrator and process of dumping of crushed gold ore is executed with the aid of spreader. EFFECT: raised efficiency of trapping of fine and thin gold, improved ecology of processed deposit. 2 dwg
