一、前言辐射分选是一种大块矿石(粒度为200—25毫米)的预选方法,它是利用各种电磁波与矿石作用后,矿石发射、反射、吸收射线能力的差别而将矿石与废石分开的一种选矿方法。一个矿区的矿石能否用辐射分选法对矿石进行预选,丢弃废石,主要由三个因素确定:采出矿块间品位分布的均匀程度、分选标志与有用元素品位的符合程度及矿石的粒度组成情况。本文将从上述三方面的内容介绍幅射分选可选性的研究方法。二、采出矿石品位分布情况的研究有用元素在采出矿块间分布的差异是辐射分选(也是各种预选方法)的基础。分布情况对能否进行辐射分选及可能获得的工艺指标有重要影响。
I. Introduction Radiation sorting is a preselected method for large ore (200-25 mm in size). It uses the difference between the ability of the ore to emit, reflect and absorb radiation after various electromagnetic waves and ore are used, A separate method of mineral processing. Whether ore in a mining area can be pre-selected by the radiation sorting method and discarded waste rock is mainly determined by three factors: the evenness of the grade distribution between the ore blocks, the conformity of the sorting marks with the grade of the useful elements and the ore Particle size composition of the situation. This article will introduce the above three aspects of the study of radiation sorting options. Second, mining grade distribution of ore Research useful elements in the mining block distribution differences are radiation sorting (also a variety of pre-selection method) basis. The distribution of radiation on the ability to sort and process parameters may have a significant impact.
