一、鞍山式鉄矿的工业意义和几年来所查明的埋藏量鞍山式鉄矿是一种含鉄量較低的含鉄石英岩,主要組成矿物为磁鉄矿(或赤鉄矿)和石英,鉄的含量一般均在30～35％,由于鉄矿物和石英往往形成薄的瓦层而呈条紋状,故又有条紋状鉄矿之称。鞍山式鉄矿虽然含鉄量較低,但由于它一般是规模巨大,又便于大规模的露天开采,同时矿石結构呈均粒状,有利于选矿(一般100～200篩目),特別是在此鉄矿层內还蕴藏着富鉄矿床,一般品位高者可达60％,硫和磷均低,适于直接作馬丁爐用的原矿石,因而它就具有极大的經济意义。鞍鋼地質勘探公司在经济恢复时期便开始着手了鞍山式鉄矿床的普查勘探工作,十年來在党和上級的正确領导和关怀下,以及全国人民的支持与全体职工 First, the industrial significance of Anshan-style 鉄 埋 and the burial amount ascertained in recent years Anshan-type 鉄-mine is a kind of quartzite containing 鉄 with low content, mainly composed of magnetite ore (or red mine) and quartz,鉄 content are generally 30 to 35%, due to 鉄 minerals and quartz tend to form a thin layer of tile and was striped, so there are striped 鉄 mine said. Although the content of Anshan-type 鉄 ore is low, it is generally large scale and convenient for large-scale open-pit mining. At the same time, the structure of ore is grainy, which is beneficial for ore dressing (generally 100-200 mesh), especially in this area The mine is also rich in Fu 鉄 deposits, the average grade of up to 60%, both sulfur and phosphorus are low, suitable for direct use as raw ore for the Martin furnace, so it has great economic significance. Anshan Iron and Steel Geological Exploration Company in the economic recovery period began its investigation of Anshan-type 鉄 deposits census work, ten years in the party and superiors under the correct leadership and care, as well as the people’s support and the entire staff
