近年来,湘潭锰矿由于300米~3锰铁高炉投产,渣量增多,但作为水泥生产原料之一的火渣却因国家基建削减而滞销。由此该矿每年有18万吨左右火渣被倒掉。这不仅使其中的锰铁不能回收,而且还为增加堆场而要征收农田数亩,(每亩10万元),并还造成环境污染。现该矿已采纳生产处康忠恕等同志提出 In recent years, the Xiangtan manganese ore has been put into production due to the 300-3M ferromanganese blast furnace, and the amount of slag has increased. However, as one of the raw materials for cement production, the slag is sluggish due to the reduction of national infrastructure. Thus the mine every year about 180,000 tons of slag was drained. This not only made it impossible to recover the ferromanganese, but also required the acquisition of a few mu of farmland for increasing the yard (100,000 yuan per mu) and also caused environmental pollution. Now the mine has adopted the production department Kang Zhongshu and other comrades
