摘要
用MgCl2溶液对赤泥进行处理,在加热和搅拌的条件下可以使赤泥中Na2O含量降低到0.13%。常温常压条件下用MgCl2溶液或人工海水处理赤泥,经浸泡也可以使赤泥中Na2O含量降低到0.8%以下,满足作为工业生产水泥原料的要求。
It is possible to decrease the content of alkali in red mud to lower than 0.13%, with heating and mixing. Then at the normal atmospheric temperature, it was also possible to decrease to lower than 0.8%. At the same condition, the artificial sea can also achieve the same result. It can meet the requirement on raw materials of the cement production.
