大红山矿区由一个大型富铁矿和一个大型铁铜矿组成,是一个火山喷发沉积矿床.主要含铁矿物为磁铁矿,其次为赤铁矿;主要含铜矿物为黄铜矿,是我省发现的规模大、质量好的铁铜矿资源.但是,占矿石总储量80%的主矿体是一个埋藏很深(约600-900米)的盲矿体,因此矿体开拓工程复杂,采矿成本高,对大红山铁铜资源的开发利用影响较大.
The Dahongshan mine area is composed of a large iron-rich ore and a large iron-copper mine, and is a volcanic eruption sedimentary deposit with the main iron-bearing minerals being magnetite followed by hematite and the major copper-bearing minerals being chalcopyrite , Is a large-scale and good-quality iron-copper mine discovered in our province.However, the main ore body, which accounts for 80% of the total ore reserves, is a blind ore body buried deeply (about 600-900 m) Complex engineering, high cost of mining, Dahongshan iron and copper resources development and utilization of greater impact.
