一些野外勘探隊正在利用重砂分析的方法來計算砂锡礦中錫石的含量。现在根据这方面工作的点滴体会,談談如何利用薄膜反应后把錫石从重砂中分离出來,直接称得錫石重量來求得錫石在重砂中的品位。从重砂中把錫石区分出來,固然可以根据錫石所固有的一定的光学性質、物理性質及化学性質來加以确定,但这种方法畢竟是有一些困难的,它要求具备一定的光性矿物学以及普通矿物学的知識,而初学的人是不易掌握的。如果利用薄膜反应的方法就方便得
Some field exploration teams are using the method of heavy sand analysis to calculate the content of cassiterite in sand tin ore. Now based on this work bit by bit experience, talk about how to use the film after the reaction of cassiterite from the heavy sand in the direct weight of cassiterite to determine cassiterite in the heavy sand grade. Judging from the heavy sands of cassiterite, although according to cassiterite inherent certain optical, physical and chemical properties to be determined, but this method is, after all, some difficulties, it requires a certain degree of photochemical minerals Learn and general mineralogy knowledge, and beginners who are not easy to grasp. If the use of thin film reaction method is convenient
