本文叙述的氢离子(H~+)过程是,用过量的硫酸在120～140℃温度下处理铝矿石3～5小时,溶出矿石所含氧化铝总量的90％左右。如此长的溶出时间,需要大型溶出器,造价昂贵。如能提高氧化铝溶出速度,减少溶出时 The hydrogen ion (H ~ +) process described in this paper is that the aluminum ore is treated with excess sulfuric acid at 120-140 ° C for 3-5 hours to dissolve about 90% of the total amount of alumina contained in the ore. Such a long dissolution time, requiring large-scale dissolution, costly. If you can improve the dissolution rate of alumina to reduce the dissolution time
