矿物分离,无论在矿物学工作中或地质找矿工作中都具有重要意义。开展矿物学工作,对矿物进行测试,如X光粉晶数据测量、化学成分分析、比重测定等,都需要一定量的单矿物,必须进行矿物分离。因此,毫不夸张地说,矿物分离是矿物学工作的基础和前提。 自然金,由于其含量低(一般×—××克/吨),颗粒细微(大多在0.1毫米以下,甚至几微米或1微米以下),往往难以分离和提纯,如完全用物理方法分离,分离时间长,劳动强度大,还得不到满意结果。 我们在《中国金矿物志》专题工作中,对分离不同矿物组合中的自然金(包括银金
Mineral separation, both in mineralogy or geological prospecting work is of great significance. Mineralogy work carried out to test the minerals, such as X-ray crystallographic data measurement, chemical composition analysis, the proportion of determination, etc., require a certain amount of single mineral, mineral separation must be carried out. Therefore, it is no exaggeration to say that mineral separation is the basis and premise of mineralogical work. Natural gold, due to its low content (usually × - ×× g / ton), fine particles (mostly below 0.1 mm, or even a few microns or 1 micron) is often difficult to separate and purify, such as complete physical separation, separation A long time, labor-intensive, but also not satisfied with the results. In the special work of “China’s Gold Mineralization”, we have made great efforts to separate natural gold (including silver
