利用矿物的磁性分离矿物,是沉积岩研究和重砂矿物分析的重要工序之一。在实际工作中,作者采用了索契涅夫万能磁鉄分选重砂矿物,收到良好的成效。該磁鉄的特点是使用方便,結構簡單,便于携帶,尤其适宜于没有电源的情况下使用。兹就其構造和使用方法作一扼要介紹。 Magnetic separation of minerals using minerals is one of the important processes in the study of sedimentary rocks and heavy sand mineral analysis. In practical work, the author adopted the Sochi Nep Giga magnetic sorting heavy sand minerals, received good results. The magnetic 鉄 is characterized by easy to use, simple structure, easy to carry, especially suitable for use without power supply. Here’s a brief overview of how it is constructed and used.
