薄膜反应方法在普查找矿时用来鉴别重砂中某些金属矿物是简、快、准的有效方法之一.该法简单易行,只需一台双目镜或放大镜,一小颗矿物样品,一小滴普通溶剂和一段铝线.反应后,薄膜性状稳定,一般在一分钟内即可完成检验工作.反应薄膜多在矿物表层进行,厚仅数微 The thin film reaction method is one of the simple, fast, and accurate methods for identifying certain metallic minerals in heavy sand during prospecting for census.The method is simple and easy to use, just a binocular or a magnifying glass, a small mineral Sample, a small drop of ordinary solvent and a section of aluminum wire.After the reaction, the film is stable, usually within one minute to complete the inspection work.Reflective film and more in the mineral surface, only a few micro-thick
