前言复杂分选定义为:旨在通过多次分选实现产出精矿和尾矿的分选过程。这种分选过程的复杂程度和再处理的全貌大概可举锡矿石重选回路说明。锡矿选矿的一般特点是:锡是一种价值很高的矿产品,但必须通过选矿制得合乎一定的市场规格的精矿;由于使用的选矿方法只有中等精确度和矿物连生问题,或者由于矿物连生问题,而无法用一段分选达到最经济的分离。这样的选厂的最佳化一般是根据生产经验和现厂试验的逐步评价进行的。对于像浮选那样的,用数学模
Preface Complex sorting is defined as a process designed to achieve the separation of output concentrates and tailings by multiple sorting. The complexity of this sorting process and the overall picture of reprocessing may be explained by the tin ore re-selection circuit. The general characteristics of tin ore beneficiation are: Tin is a very valuable mineral, but concentrates must be prepared by beneficiation to the extent that they meet certain market specifications. Because of the use of beneficiation methods that have only moderate accuracy and mineral concurrence, or As a result of mineral problems, but can not use a sorting to achieve the most economical separation. The optimization of such plant selection is generally based on a step-by-step evaluation of the production experience and on-site tests. For flotation like that, use mathematical modules
