近年来,东德弗顿贝格选矿研究所日益加强对各类石英、石灰石和玻璃原料的光选研究。此种方法已被用于机械或化学选矿以及达到最终产品所需品级前的预处理作业。它适用于从生产色泽鲜艳的颜料或填充济以及需要高光亮度作为一种质量特征的原矿中,分选出暗色组价。下面将阐述光选机用于石英原矿预处理作业的可能性和条件。分选高级石英原矿的可能性光学工业和其它特种玻璃工厂需求高级石英原矿。因此,原矿中仅允许含有低百分比的带色重金属氧
In recent years, the East Dreddon Beg ore beneficiation Institute is increasingly strengthening the light selection of various types of quartz, limestone and glass raw materials. This method has been used for mechanical or chemical beneficiation and pre-treatment operations to the grade required for the final product. It is suitable for sorting dark color sets from raw ore that produces brightly colored pigments or finishes, and that requires high brightness as a quality feature. The following will explain the possibility and conditions for using light preselector for quartz ore pretreatment. Possibility of Sorting Superior Quartz Ores Optical industry and other specialty glass plants demand advanced quartz ore. Therefore, only a low percentage of colored heavy metal oxygen is allowed in the raw ore
