这里所指的选别作业的给料是二组分的混合物,产品只有两个,一个是有用矿物(或矿质)的富集产物——精矿;一个是无用脉石矿物(或矿质)的富集产物——尾矿。评定选别作业效果好坏的指标常用的有四个即:精矿(或尾矿)产率、有用成份回收率、富集度和选矿效率。这四个指标之间有什么关系,值的范围与品位变化的联系,本文做了阐述。并举了两个实际应用的例子。对任意选别作业,其给矿和产品的量和质表示如下:(如图1)
As used herein, the feed for a sorting operation is a two-component mixture of only two products, one being a concentrate of useful minerals (or minerals) - a concentrate of unwanted gangue minerals (or minerals) Enriched product - tailings. There are four commonly used indicators to assess the performance of sorting operations, namely, the yield of concentrate (or tailings), the recovery of useful components, the enrichment and the efficiency of mineral processing. What is the relationship between the four indicators, the range of values and the relationship between grade changes, this article has elaborated. Cited two examples of practical application. For any sorting operation, the quantity and quality of the ore and products are as follows (as shown in Figure 1)
