我国高Al_2O_3、高MgO铁矿床分布很广,遍及很多省区,有的高Al_2O_3,有的高MgO,有的二者都高。如湖南攸县铁厂,湘华铁厂,云南富源铁厂,广东韶钢,广西柳钢,渣中Al_2O_3含量均可达20％以上,有的甚至高达25％～30％。河北涞源铁矿、陕西大西沟精矿以及西石门铁矿、铜厂铁矿、天湖铁矿等含MgO均高,如单独用这些矿冶炼,渣中MgO含量可达25％甚至30％以上。此外如山东张家洼小官庄精矿,浙江漓渚西矿等则MgO、Al_2O_3均高,渣中MgO、Al_2O_3
China’s high Al_2O_3, high MgO iron deposits are widely distributed in many provinces and regions, some high Al 2 O 3, some high MgO, and some are high. For example, Hunan Youxian Iron Works, Xianghua Iron Works, Yunnan Fuyuan Iron Works, Guangdong Shaoguan Iron and Steel, Guangxi Liuzhou Iron and Steel, slag Al_2O_3 content can reach more than 20%, and some even as high as 25% to 30%. Hebei Huangyuan Iron Mine, Shaanxi Daxigou Concentrate, Xishimen Iron Mine, Tongchang Iron Mine and Tianhu Iron Mine have high MgO content. If these mines are used solely for smelting, the MgO content in the slag can reach 25% or even 30% the above. In addition, such as Xiaoguanzhuang Concentrate in Zhangjiawa, Shandong Province and Lizhu West Mine in Zhejiang Province, the contents of MgO and Al 2 O 3 are high, and the contents of MgO, Al 2 O 3
