铋在亲铜元素的硫化物中富集存在,在地壳中平均含0.17ppm,含Bi矿物很多,自然铋(Bi)和辉铋矿(Bi_2S_3)是最普遍的。铋的产出以气成矿床、高温交代矿床、热液矿床为主。没有形成单独的矿床,多与锡、钨、铜、金等共生赋存。估计世界上铋的储藏量为9.4万吨,全部矿量的24％赋存在日本,但是铋的地球化学还没有研究,不清楚的问题还很多,对铋的存在状况没调查的地区还很多。单独形成铋的矿床还没有,因为大部分是从铅、铜等其他金属的冶炼过程中作为副 Bismuth is enriched in copper-rich sulfides, with an average of 0.17ppm in the crust. There are many Bi minerals, and natural bismuth (Bi) and bismuthinite (Bi_2S_3) are the most common. The output of bismuth gas-bearing deposits, high-temperature replacement deposits, hydrothermal deposits dominated. Did not form a separate deposit, and more with tin, tungsten, copper, gold and other symbiotic occurrence. It is estimated that the world’s reserves of bismuth are 94,000 tons and 24% of the total amount is in Japan. However, the geochemistry of bismuth has not been studied. There are still many problems that are unclear. There are still many areas that have not been investigated on the existence of bismuth. Bismuth deposits alone have not yet, because most of the other metals from the lead, copper and other smelting process as Vice
