| 摘 要： | 鞍山黑石砬子铁矿床位于东鞍山铁矿与大孤山铁矿之间，是近年来鞍本地区发现的大型铁矿床.Ⅱ-1号矿体是主要的工业矿体，延长2000余米，水平厚度百余米，控制延深1000余米.有用矿物主要为磁铁矿和赤铁矿，矿体品位在走向和垂向上基本稳定，但FeO有随深度增加而增加的趋势.矿石化学成分和矿物组成简单，有害物质含量低，矿体中夹石率较低，属于沉积变质型的鞍山式铁矿床.

| Abstract: | The Heishilazi iron deposit,which lies between Donganshan iron mine and Dagushan iron mine in Anshan,Liaoning Province,is a large iron deposit of Anshan type found in Anshan-Benxi area recently. The Ⅱ -1 ore body is the major industrial one,with length of over 2000 m,horizontal thickness of more than 100 m and controlled depth of about 2000 m. The useful minerals are mainly magnetite and hematite. The grade is steady in strike and vertically,but the FeO content gradually increases with the increasing of the depth. The chemical and mineral components are simple,with less deleterious impurities and low ratio of horse-rocks. All these indicate that the ore deposit belongs to sedimentary-metamorphic iron deposit of Anshan type. |
