摘要
浙江长兴硅灰石伴生有方解石(大理岩),主要开采对象为硅灰石,以往将大部分方解石(大理岩)作为围岩废石进行剔除,回采率低,浪费了资源。通过技术改造,采用综合开采技术,在回采硅灰石的同时,开采回收伴生方解石,可提高矿产资源综合利用率,增加经济效益。
Wollastonite is associated with calcite(marble) in Zhejiang Changxin, wollastonite is mining main object. In the past, the most part of calcite(marble) as the rock were eliminated, the recovery rate is low, resources had been wasted. Through technical transformation, by the comprehensive mining technology,associated mineral calcite can be recycled at the same time of mining wollastonite. It can improve the comprehensive utilization rate of mineral resources, increase economic benefits.
