三、马山埠铁矿(一)概况马山埠铁矿为县社联营小型露天矿山,半机械化开采,初步形成年产3万吨矿石的小型矿山。由于该矿从1958年人工开采以来堆积近40万吨粉矿(矿层土),以及目前采矿过程随原矿品位降低其粉矿也无法外销。为了充分利用与扩大矿产资源,该矿于1974年开始兴建洗矿设施,在黄梅山铁矿大力支援下,洗矿设施于1976年元月投产。自生产以来,设备运转正常,效果显著。
3. Maanshan Port Iron Ore (I) Overview The Ma'anshan Iron Ore is a small-scale mine with a combined annual output of 30,000 tons of ore, which is a small-scale open-pit mine jointly operated by the county and society and semi-mechanized mining. Due to the accumulation of nearly 400,000 tons of fine ore (ore bed) since the mine was artificially mined in 1958, the current mining process can not be exported as its ore grade is reduced. In order to make full use of and expand mineral resources, the mine started construction of washing facilities in 1974. With the great support from Huangmeishan Iron Mine, the ore washing facilities were put into operation in January 1976. Since production, the equipment is operating normally and the result is remarkable.
