概况 按矿石色泽进行分选,是一种很古老的方法,如手选法仍在使用,但生产率低,劳动强度大。后来发展了若干种根据色泽来分选的机械选矿机,也因产量低,效果不好而未获推广。 多年来,各种选矿技术都受工作原理的限制,仍不能解决某些矿石分选问题,如当精矿同杂质之间的比重(如本文下面介绍的 Overview Sorting by ore color is a very ancient method, such as the hand selection method is still in use, but low productivity, labor-intensive. Later developed a number of sorting machine according to the color of mineral concentrator, but also because of low output, the effect is not good and not promoted. Over the years, all kinds of mineral processing technology are subject to the working principle of the restrictions still can not solve some of the ore sorting problems, such as when the concentrate and the proportion of impurities (as described below
