辉绿岩饰面石材矿废石利用探讨

Discussion on Waste Stone Use in Diabase Facing Stone Ore Development

内蒙丰镇、山西浑源和河北阜平一带辉绿岩早期只开采饰面石材,不能成荒料的辉绿岩作为废石处理,堆积了大量的辉绿岩碎石。通过研究内蒙丰镇、山西浑源和河北阜平辉绿岩的物理、化学特征,与纤维、岩棉、铸石材料及制品主要矿石原料的指标要求进行对比分析,辉绿岩饰面石材矿的"废石"可以用于生产纤维、岩棉、铸石材料及制品,只是因不同地方辉绿岩基性程度不同,需要添加不同量的配料进行调剂。对以后科学地开发辉绿岩资源具有指导意义。

In the early stage of diabase in Fengzhen of Inner Mongolia,Hunyuan of Shanxi and Fuping of Hebei,only facing stone was mined,and diabase that could not be made into waste rock was treated as waste rock,and a large amount of diabase gravel was accumulated.By studying the Inner Mongolia Xinfeng,muddy source in Shanxi and Hebei Fuping physical and chemical characteristics of diabase,and fiber,rock wool,cast stone index of main mineral raw materials and products requirements,this paper compares and analyzes diabase facing stone mine"dirt"can be used in the production of fiber and rock wool,cast stone materials and products,only because of different local diabasic batholith at different levels,different amounts of ingredients need to be added to adjust.It is of guiding significance to develop diabase resources scientifically in the future.
