Method for extracting iron from high-iron red mud and directly preparing cement raw material
The invention discloses a method for extracting iron from high-iron red mud and directly preparing a cement raw material, which is characterized in that the high-iron red mud is prepared from the following materials in percentage by weight: 35-40% of silicon dioxide, 40-45% of calcium oxide, 5-10% of ferric oxide, 3-5% of aluminum oxide and 1-2% of trace elements, the required materials are high-iron red mud, anthracite, a modifier, lime, a reducing agent, granulated blast furnace slag, gypsum, reducing gas and inert gas. Compared with the prior art, the method has the advantages that processing can be rapidly carried out, iron and cement can be conveniently extracted, and the actual cost of the cement can be reduced.
本发明公开了一种高铁赤泥提铁及直接水泥原料的方法，其特征在于：所述高铁赤泥选取材料占比为二氧化硅35～40％、一氧化钙40～45％、三氧化二铁5～10％、三氧化二铝3～5％、微量元素1～2％，所需要的材料为：高铁赤泥、无烟煤、改性剂、石灰、还原剂、粒化高炉矿渣、石膏、还原气体和惰性气体。本发明与现有的技术相比的优点在于：本发明可以快速进行加工、能够方便提取铁和水泥、可以降低水泥的实际成本。
