第一节总论钼和钨常互相共存于矿石中,甚至形成含两种元素的矿物。从矿物学上看钼和钨的主要差别是硫化钼——辉钼矿分散性大,而硫化钨却矿化现象少。钨和钼的氧化矿物——钼钙矿和白钨矿以及黑钨矿的结构和浮选特性相近。钼和钨矿物的共同性是比重大。存在两种钼和钨伴生矿石的成因分类:1)在石英矿脉中含有或与云英岩伴生的辉钼矿、黑钨矿和黄铁矿的热液矿床;2)由硅酸钙、硅酸铁和硅酸铝构成的斯卡隆矿石。斯卡
The first section General molybdenum and tungsten often coexist in the ore with each other, and even the formation of two kinds of minerals. In mineralogy, the main difference between molybdenum and tungsten is the dispersibility of molybdenum sulfide-molybdenite and the fact that tungsten sulfide is less mineralized. The structural and flotation characteristics of the tungsten and molybdenum oxide minerals, molybdenite and scheelite, and wolframite are similar. The commonality of molybdenum and tungsten minerals is significant. There are two types of genesis of molybdenum and tungsten associated ores: 1) hydrothermal deposits of molybdenite, wolframite and pyrite associated or associated with dolomite in quartz veins; 2) silicates consisting of calcium silicate, silicon Skullite ore composed of acid iron and aluminum silicate.
