在一般条件下,对云母一类片状矿物的分离提纯比较困难,显微镜下的工作量较大。1976年黑龙江省地质局实验室曾制造了矿物形态分离仪,对于片状矿物具一定选纯效果。笔者在该仪器分选原理的基础上,对结构、元件作了改进,尽量利用廉价材料,试制了一台简易矿物形态分离仪。结构简单,成本低,坚固耐用。经初步实验,分选效果尚可,现介绍如下。
Under normal conditions, it is difficult to separate and purify a group of minerals such as mica, and the workload under the microscope is relatively large. In 1976, the laboratory of Heilongjiang Province Geological Bureau had made the mineral form separation apparatus, which has certain pure effect on the flaky minerals. Based on the sorting principle of the instrument, the author made improvements to the structure and components, tried to make use of cheap materials and tried out a simple mineral form separator. Simple structure, low cost, durable. After a preliminary experiment, the sorting effect is acceptable, are presented below.
