一、前言氧化鋁渣是制鋁工业从鋁土矿中提炼氧化鋁后所排出的残渣,又名赤泥,其数量一般为氧化鋁产量的1—2倍以上。鋁土矿品位愈低,单位氧化鋁生产的残渣排出量就愈大,它的利用是一个十分重要的問题。如果氧化铝渣能被广泛的綜合利用,制成有用的副产品,则不仅可以解决庞大的氧化鋁渣堆场問題,从根本上減輕或消除氧化鋁渣对农田的危害,而且可以充分地利用資源,給国民經济建設带來重大的收益,使 First, the preface Alumina slag is the aluminum industry from the bauxite after the extraction of alumina residue, also known as red mud, the amount of alumina production is generally more than 1-2 times. The lower the grade of bauxite, the greater the amount of residue produced per unit of alumina production. Its utilization is a very important issue. If the alumina slag can be widely used comprehensively to make useful by-products, it not only can solve the problem of huge alumina residue yard, but also fundamentally reduce or eliminate the harm of alumina residue to farmland, and can make full use of resources , Bringing major benefits to the construction of the national economy
