有效地回收细粒、微细粒浸染的有用矿物,是近代国内外选矿界重要的研究课题之一。由于受能源、环境保护和市场需求等因素的制约,在诸种选矿方法中,细粒重选技术具有单位生产费用比浮选低、设备功率低、不污染环境等优点,显示了较强的竞争力。近些年来,我国细粒重选在设备研制和应用技术上大有进展。六十年代研制出具有我国独特风格的离心选矿机,七十年代研制成了复合运动的振摆皮带溜槽。现在研制和用于生产的细粒重选设备品种繁多:间歇分选的有自动溜槽,摇动翻
It is one of the most important research topics in mineral processing community at home and abroad to effectively recover the useful minerals that are fines and fine particles. Due to energy, environmental protection and market demand and other factors, in a variety of beneficiation methods, the fine grained re-election technology has the unit cost of production than the low flotation, low power equipment, does not pollute the environment, etc., showing a strong Competitiveness. In recent years, China’s finer grading has made great progress in equipment development and application technology. Sixties developed with our unique style of centrifugal concentrator, developed in the seventies complex movement of the swing belt chute. Now developed and used in the production of fine grain re-election a wide range of equipment: intermittent sorting automatic chute, shaking turn
