【摘要】 随着我国有色金属资源特点日趋复杂、贫、细,开发利用低品位矿对于选矿业的发展显得尤为重要。通过总结铝、铜、镍、钒的选矿技术进展,论述了选矿-拜耳法生产氧化铝(浮选脱硅工艺流程,浮选药剂)、低品位铜矿(浮选柱、地浸技术)、镍矿分选的离析-选矿工艺、常压浸出工艺、生物浸出工艺以及石煤型钒矿提钒技术等的研发及矿物分选新理念几个方面的内容,并对今后技术的发展作了介绍。更多还原

【Abstract】 Since the non-ferrous metal resources in our country are becoming more complex,lean and finer,it is very important for ore-dressing industries to exploit and make use of the low grade ores.Through summarizing the technical progresses on beneficiation of aluminum,copper,nickel and vanadium ores,several new ideas of research and development and some beneficiation technologies including producing the alumina in the Bayer process,the leaching-beneficiation of low grade copper ores and nickel ores,normal pressure leaching technique,biological leaching technique and vanadium extraction technique from bone coal vanadium ores are discussed.Then the developments of some techniques in future are introduced.更多还原
