泥里钻金岂不是天方夜谭?其实不然,关键是看泥中含有何物。转炉冶炼过程中生成的乌黑油亮的尘泥,就能钻出灿灿的乌金来。 转炉冶炼中产生的烟尘,经湿法工艺除尘后就成了黑油油的污泥,其黑漆程度足可与徽墨上品顶漆烟相媲美;数量约占钢产量的2％,它含有50％以上的铁和相当数量的氧化钙、氧化锰、氧化镁等碱性氧化物。若将其废弃,则占用大片土地、污染环境、流失宝贵的二次资 Is it a fantasy in the mud? In actual fact, the key is to see what is contained in the mud. Converter generated during the smelting black glossy oil dust, will be able to drill awesome black gold. Soot produced in the converter smelting, after the wet process dust became black oil sludge, the degree of black paint enough with the emblem of the top paint smoke comparable; the amount of about 2% of steel production, which contains more than 50% Iron and a considerable amount of calcium oxide, manganese oxide, magnesium oxide and other basic oxides. If they are abandoned, they occupy a large area of ​​land, polluting the environment and losing precious secondary funding
