摘要
南川市石英砂矿产资源丰富,但不同矿区矿石的SiO2、Fe2O3及Al2O3的含量差异比较大,如果对各个矿区采用一种开发方式,势必影响石英砂岩的使用范围和经济价值。结合南川市的矿产资源开发利用规划,对该市石英砂岩的分布特点及赋存条件进行了分析,指出目前该市石英砂岩加工利用方面的不足。为了提高南川市石英砂岩利用的经济效益,认为有必要对南川市的石英砂岩进行分矿区、分优劣进行开采加工,对优质的石英砂岩进一步深加工,对尾矿也要充分利用。
Quartz resource is abundant in Nanchuan, but there is large difference of the contents of SiO2, Fe2O3 and Al2O3 in different mineral fields. The using range and economical value of quartz resource are limited if the every mineral field is exploited by the same way. Based on the minerals resource developing and utilization project of Nanchuan, this article analyzes the distribution characters and existing conditions of quartz deposit in Nanchuan, and points out the problems in processing and using quartz in Nanchuan, considers that the quartz sandstone depos should be exploited using different ways in accordance with different mineral fields and the quality of quartz ore, and good quality quartz sandstone should be deep processed fatherly in order to improve the economical effect of utilizing quartz sandstone resource, as well as the tails should be made full use of.
