近年来,在非金属有用矿物加工领域中,辐射分选技术愈来愈加发展,借助这种方法可以解决两个基本问题:预选原矿,即去除有用组分含量不合格的大块部分;获得块状商品精矿。本文阐述了用辐射法选别非金属有用矿物的最有前景的荧光分选法。这种矿物分为四类:化工矿物类;工业矿物类;建材类和宝石类。第一类原矿为硼类(硅钙硼石、赛黄晶)、磷酸盐类(磷灰石、磷钙土)和无机盐类(钾石盐);第二类为萤石类和钡类矿石;第三类包括陶瓷原料(微斜长石、斜长石、硅灰
In recent years, in the field of useful processing of non-metallic minerals, radiation sorting technology is more and more developed, with the help of this method can solve two basic problems: pre-selected ore, that is, removal of unwanted content of useful components of the bulk; Commodity concentrate. This article describes the most promising fluorescence sorting method for determining non-metallic useful minerals by radiation. This mineral is divided into four categories: chemical minerals; industrial minerals; building materials and gems. The first type of ore is boron (silicon-calcium-boron stone, racemectin), phosphate (apatite, calcium carbonate soil) and inorganic salts (potassium salt); the second category is fluorite and barium Ore; the third category includes ceramic raw materials (plagioclase, plagioclase, silica fume
