摘 要 为促进矿产资源综合勘查评价利用,文章以矽卡岩型铁矿床为研究对象,通过对典型矿床地质特征及矿山实际开采利用资料的分析,总结了其共伴生矿产特征,并采用“回收度”指标评价了矽卡岩型铁矿床伴生矿产的综合回收情况。研究表明矽卡岩型铁矿床共伴生矿产非常丰富,共近30种;随岩浆岩的酸性变化,矿化组合由单一的铁矿,渐变为铁铜钴、铁锡锌、铁锡钨钼等多金属组合;共伴生矿产的综合回收情况较好。

Abstract: In order to promote the comprehensive exploration and utilization of mineral resources,through the analysis of the ore geological characteristics and the actual mining utilization data of several typical skarn iron deposits in China,authors summarized the combined char-acteristics of the associated components . Studies have shown that the associated minerals of skarn-type iron deposits are very rich, with a total of nearly 30 kinds; with the acidity of magmatic rocks, the mineralization combination changes from a single iron ore to iron-cobalt-cobalt, iron-tin-zinc, iron-tin-tungsten-molybdenum And other multi-metal combinations; the comprehensive recovery of associated minerals is generally well.
Keywords: comprehensive recovery;associated minerals;comprehensive exploration;skarn iron deposits
礦产资源因其有限性、不可再生性以及多组分伴(共)生等特点[1],世界各主要矿业开发国对矿产资源的综合回收利用都非常重视[2,5],尤其我国是人口大国,虽许多矿产资源储量位居世界前列,但人均拥有量远低于世界平均水平[4] ,加强矿产资源综合勘查评价、加强矿产资源节约与综合回收利用、推进生态文明建设更加重要[5]。而对矿产资源共伴生矿产的特征研究是其综合回收利用研究的基础。
矽卡岩型铁矿床是我国主要铁矿床类型,也是重要富铁矿类型之一,其共伴生组分非常丰富[6]。前人对矽卡岩型铁矿床中共伴生矿产的研究往往聚焦于某一个矿床或某一种类型[7],没有对这一类别矿床的共伴生矿产进行整体研究,尤其缺乏对目前我国矽卡岩型铁矿床中共伴生矿产的综合回收水平的研究。……
