选矿厂的基本任务是把有用矿物和脉石分离,选出有用矿物富集的精矿以供提炼金属—给冶炼厂做原料。大多数选矿厂都是凭实践经验,用肉眼来判断流程各作业的产品质量。尤其是入选矿石品位,决定添加选矿药剂的多少,操作条件,精矿质量的稳定提高,不仅增加矿山的经济效益,而且还挖掘冶炼的能力。相应的减少投资、材料、燃料、动力消耗。降低冶炼成本,提高冶炼回收率,同时标志着选矿的科学技术管理水平。 The basic task of the concentrator is to separate the useful minerals from the gangue and to pick up the concentrate enriched with the useful minerals for refining the metal - to feed the smelter. Most beneficiation plants are based on practical experience, with the naked eye to determine the quality of the process of operation of the product. In particular, the grade of the selected ore, decided to add the number of beneficiation agents, operating conditions, the steady improvement of the quality of the concentrate, not only increase the economic benefits of mines, but also tap the ability of smelting. The corresponding reduction in investment, materials, fuel, power consumption. Reduce the cost of smelting, increase smelting recovery, and at the same time mark the level of scientific and technological management of beneficiation.
