补充资料：伴生矿
伴生矿
associated ore
bonsheng kuang伴生矿(~iatedore)在同一矿床(矿体)内，不具备单独开采价值，但能与其伴生的主要矿产一起被开采利用的有用矿物或元素。例如，斑岩铜矿床中的铂、锌、金等，黑钨矿石英脉矿床中的锡、钥、敏、妮、担、秘和水晶等。伴生矿是相对主要矿产而言，由于它们具有相似的地球化学性质和共同的物质来源，因而常伴生在同一矿床(矿体)内。伴生矿或赋存在独立矿物中，如斑岩铜矿中的辉铝矿;或呈类质同象或机械微细混人物被包含在主要矿产的矿物中，如方铅矿、闪锌矿中的锡、锢、稼、锗等。要仔细研究它们赋存状态和分布特征，以便采用合理的选矿、冶炼工艺流程，加以回收和综合利用。 (黄华盛)
