中国矽卡岩型矿床尾矿的综合利用现状

The state of the comprehensive utilization of Skarn-type deposits tailings

矽卡岩型矿床是我国铁、铜、铅、锌、银、钼、钨、锡等多种矿床的主要类型。该类矿床多为共伴生矿,金属矿物成分复杂;非金属矿物石榴石、硅灰石、透辉石、透闪石等大多具有工业价值。本文通过对矽卡岩型矿床及其尾矿特征、工业价值、综合利用现状进行总结,阐明了综合回收利用矽卡岩型矿床尾矿中的微量金属和组成矽卡岩的大量非金属矿物,可以提高经济效益,减少尾矿数量,降低尾矿危害。并建议相关部门选取典型矿床类型、典型矿种开展尾矿综合利用研究。

Skarn-type deposits are the main types of iron, copper, lead, zinc, silver, molybdenum, tungsten, tin, and other multiple deposits. This type of deposits is most co-associated minerals deposit, and the metal mineral compositions are complex non metallic mineral garnet, wollastonite, diopside, tremolite, etc. most have industrial value. In this article, through summarizing the skarn-type deposit and its tailings＇ characteristics, industrial value and comprehensive utilization state, clarifying that the comprehensive recycling of trace metals in skarn-type deposit tailings and large number of non-metallic minerals compositing the skarn can improve economic efficiency, decrease tailings quantity, reduce tailings hazards. We suggested that the relevant departments to select a typical deposit types,typical minerals to carry out the comprehensive utilization research.
