河北某磷矿是我国北方地区一个储量大,易选、中低品位磷铁矿床。自上而下有Ⅰ、Ⅱ、Ⅲ号主要矿体,各矿体及矿体分层的P_2O_5含量不一。选择不同的开采对象,就有不同的企业建设效果。因此,如何根据该矿矿床赋存特点和当前国内技术经济条件,实行经济合理开发,已成为有关部门共同关心的技术经济课题。笔者对此提出浅见,敬待各方批评指正
A phosphate rock in northern China is a large reserves, easy to choose, low-grade phosphorus-iron deposits. From top to bottom there are Ⅰ, Ⅱ, Ⅲ main ore body, the ore body and ore body layered P_2O_5 content is different. Choose different mining targets, there are different effects of enterprise construction. Therefore, according to the occurrence characteristics of the ore deposits and the current domestic technical and economic conditions, the implementation of economic and rational development has become a topic of technical and economic concern of the relevant departments. I made a humble opinion on this, to all parties criticism and correction
