1984年底至今年初,我们对山东省的掖县、栖霞和安徽省的江淮、肥东、宿松和凤台等六个小磷矿作了一次调查,对这些矿山的生产现状,存在问题及今后发展等有了一定程度的了解。当前,这些小磷矿都面临着提高质量,降低成本,实行综合利用等急待解决的问题,因而对这些小矿的分析无疑具有相应的意义。 对这六个小磷矿,可按地质成因类型分成三类: 1.内生岩浆型磷灰石矿床(掖县、栖霞);
From the end of 1984 to the beginning of this year, we conducted a survey of six small phosphate rock deposits in Yexian County, Qixia County in Shandong Province and Jianghuai City, Feidong County, Susong County and Fengtai County in Anhui Province. We conducted a survey on the production status, existing problems and future development of these mines Have a certain degree of understanding. At present, these small phosphate mines all face the urgent problems of improving quality, reducing costs and implementing comprehensive utilization. Therefore, the analysis of these small mines undoubtedly has corresponding significance. The six small phosphate rocks can be divided into three types according to the type of geological formation: 1. Endogenous magmatic apatite deposits (Yexian, Qixia);
