The results show that magnesium and aluminum theoretically can be thoroughly dissolved from the blast furnace slag by diluted sulfuric acid pretreatment on the blast furnace slag even if the ended concentration of sulfuric acid is 0.001mol/L, while the titanium basically could not be dissolved. Therefore it is theoretically indicated that the separation of the magnesium and aluminum from the slag with the least titanium loss by diluted sulfuric acid pretreatment is possible.
结果表明,采用稀硫酸对高炉渣进行预处理,当终酸浓度即使为0.001mol·l~(-1)时,镁、铝理论上也能全部被酸浸出,而钛在0.001 mol·l~(-1)的酸浓度条件下基本不被浸出,从而从理论上可以说明对高炉渣采用稀酸预处理可以很好的将炉渣中的镁、铝等杂质分离出来,而钛极少被浸出。
