黑钨矿是钨的主要工业矿物之一,在多种钨矿床中有较广泛的分布。由于钨、铌、钽的地球化学性质很近似,黑钨矿中往往含有一定数量的铌钽。对黑钨矿中铌钽含量及存在形式的研究,在寻找隐伏含矿岩体,研究元素演化及分析推断地球化学过程的机理与特征,确定冶炼方法及流程,搞好综合利用等方面都具有重要的意义。前人对黑钨矿的化学成份已作过许多研究,但对铌钽在黑钨矿中存在形式的研究却报道较少。现将我们对部份钨矿床中的黑钨矿所进行的研究结果报道如下:  相似文献

Gold-bearing base-metal deposit is one of the important types for gold and has received increasing attention. Results of this study show that all the gold in these ores occur us fine-grained minerals and except for tctrahedrite in which silver occurs mainly as solid solution component, silver minerals can account for most of the silver content in other ere minerals. Our study also indicates a close relationship between gold and copper, arsenic; and between silver lead and zinc. Additionally, it is noticed that the precipitation of gold is earlier than silver.  相似文献
