冀东遵化石人沟铁矿矿体分布特征及矿石加工技术性能研究

Study on ore body distribution characteristics and ore processing technology performance of Shirengou Iron Mine in Zunhua,Eastern Hebei

我国是铁矿资源丰富的国家,但是铁矿资源贫矿多、富矿少。石人沟铁矿矿石工业类为鞍山式贫磁铁矿,矿物组成简单,金属矿物主要为磁铁矿,矿石中有害成分含量较低,金属矿物可选性较好。通过深部钻探工程对矿体的控制情况,得出矿床总体呈北端翘起向南逐渐侧伏的规律。认为第20号勘探线深部矿体呈变厚趋势,预测可有较好资源量增储前景。

China is rich in iron ore resources,but the iron ore resources are rich and poor.The ore industry of Shirengou Iron Mine is Anshan type lean magnetite,with simple mineral composition.The metal mineral was mainly magnetite,with low content of harmful components in the ore and good selectivity of metal minerals.Through the control of the deep drilling project on the ore body,it was concluded that the deposit was generally inclined from the north to the south.It was considered that the deep ore body of the No.20 exploration line was becoming thicker,and it could be predicted that there was a good prospect for increasing reserves.
