摘要 系统地研究了辽宁野猪沟铁矿石的化学组成、矿物组成及嵌布特征。结果表明:矿石以鲕状构造为主,具有典型的同心环带结构。矿石中铁、锰矿物主要以粉末状和致密块状两种状态存在。粉末状赤铁矿、褐铁矿、氧化锰多形成松散的土状集合体,致密块状的赤铁矿则分布于石英砂粒周围;磁铁矿多包裹石英砂粒。矿石的上述特性造成有用矿物难以单体解离并易于泥化,因而使矿石难选。

Abstract: Systematical study on the chemical composition, mineral components, and embedded characteristics of iron ore is carried out.The research results showed that the main ore structure is oolitic with a typical band structure of concentric rings.Iron and manganese in minerals mainly are existed in states of compact and lumpy powder.Powder hematite, limonite and manganese minerals usually formed more loose earthy aggregate while dense massive hematite is distributed in the surrounding of quartz.And magnetite mainly contain a quartz sands.This above feature makes the valuable single mineral difficult to liberate and easy to be mud,so this ore is very hard to separate.
