以氢氧化铝作为后加矿,采用增溶溶出技术处理一水硬铝石矿·研究了一段溶出配料摩尔分数、增溶温度、后加矿加入量、增溶时间对溶出效果的影响·确定了增溶溶出的工艺条件:一段配料摩尔分数控制在1 55~1 60,增溶温度为210~220℃,增溶时间为15~20min,后加矿加入量为一段溶出时矿石量的10%~15%·此条件下铝土矿的溶出率达到88 8%以上,溶出液的摩尔分数降至1 4以下·结果表明,此方法可以降低溶出液的摩尔分数,提高氧化铝的溶出率
补充资料:一水硬铝石
分子式:AlO(OH)
CAS号:
性质:又称硬水铝矿。常含微量铁、锰等。斜方晶系。通常成细鳞片状集合体或结核状块体,极少呈薄板状。硬度6~7。密度3.3~3.5g/cm3。玻璃光泽,解理面呈珍珠光泽。白色、灰色、黄褐或黑褐色。性脆。解理平行,板面完全。主要形成于外生作用,广泛分布于铝土矿矿床中。山东淄博地区的“一水型”铝土矿矿床中,即以一水硬铝石为主要矿物成分。是炼铝的重要矿物原料。
