文摘The properties such as type & location,mineralogical composition,stratigraphic formation,disseminated size of Anshan iron ores from Dagushan,Donganshan,Qidashan,Guanbaoshan,Gushouyu,Hujiamiao,Zhangjiawan etc.are studied.On this basis,suggestions to promote exploitation and utilization of Anshan iron ore resources are made.
文摘一、前言在岩矿分析工作中,广大技术人员希望有一种简便的方法,测定岩石中各矿物的准确含量。特别是对于非金属矿床的有用矿物和脉石显得更为重要。而化学分析只能给出元素的百分含量,虽也包括了有用矿物和脉石矿物的成分,但不能指出该元素的存在形式。岩矿鉴定虽能查出视域中矿物的大致含量,但不能用以固定非金属矿的品位及计算储量。在寻找兰晶石基地的工作中,我们对河北省某地上寒武系黑云母斜长片麻岩中的兰晶石进行了 X
