多数锡矿都是综合性的.据?等人对苏联锡矿床的研究,约有62%的锡矿床是综合性的,另外38%是单锡矿床.在综合性矿床当中,锡的平均价值为78%,伴生组分的价值几乎等于原始矿石中金属商品价值的四分之一.锡矿中最常见的伴生组分是铜、钨、铅、锌和银,其次是铋、镉和铟,再次是钴、钽和铌.不同成因类型的矿床,其矿石物质成分是不同的.多数锡石-石英类型矿床的伴生组分价值比较小,而锡的价值则很高(91%).其中钨的价值变化范围是1.7～27.7%,铜为1.8～2%,铋为0.7～5.1%.对于这类矿床,要特别注意回收钨,因为即使钨的含量不高,顺便回收也能获利.根据锡石-
Most of the tin mines are comprehensive.According to the study of the Soviet Union’s tin deposits, about 62% of the tin deposits are comprehensive and the other 38% are single-tin deposits.In the comprehensive deposit, the average value of tin Is 78%, the value of associated components is almost equal to one-fourth of the value of the metal commodity in the raw ore.The most common associated components in tin ore are copper, tungsten, lead, zinc and silver, followed by bismuth, cadmium and indium , And again cobalt, tantalum and niobium.Different genetic types of ore deposits have different compositional compositions of minerals.Most cassiterite-quartz type deposits have relatively low value of associated components, whereas tin is of high value (91%). Among them, the value of tungsten varies from 1.7% to 27.7%, copper is 1.8% to 2%, and bismuth is 0.7% to 5.1% .With regard to such deposits, special attention should be paid to the recovery of tungsten because even if the tungsten content is not high, Lee. According to Cassiterite -
