In alkali, sodium, aluminium, fluoride and rare metal etc., it will as percolate enters underground water, certain wound is caused to human body
Evil.In addition, the high alkalinity of red mud also can contaminant water, certain harm is generated to people and animals and plants.The generation of red mud is to the mankind
Production, life cause various influences directly or indirectly, it is real so reduce yield and the harm of red mud to greatest extent
Now by all kinds of means, the recycling of big quantity it is extremely urgent.Therefore how red mud to be turned waste into wealth, waste utilization, change is harmful to have
Profit reduces the concern that all circles' researcher has been caused to naturally polluting.It is mainly reflected in following four aspects：When
The material of building trade is produced with red mud；Second is that component useful in extraction red mud；Third, preparing adsorbent；Fourth, preparing catalysis
Agent, red mud iron-holder is high, particle is small, large specific surface area, is not easy poisoning and the characteristics such as of low cost, becomes many catalysis
Agent prepares raw material, is widely used in the reaction process such as hydrogenation liquefaction, hydrogenation-dechlorination, Fenton advanced oxidations and purification exhaust gas
In.
Numerous studies are carried out to the comprehensive utilization of red mud in recent years both at home and abroad, such as using red mud production cement, using red
Mud is used as new wall material, red mud Direct reduction iron etc..But most of also in the experimental stage, the utilizing status of red mud is not
It is ideal.
