| titleOfInvention | A kind of alkali method is carried aluminium and is obtained dealkalize red mud and the application thereof of the method for dealkalize red mud and acquisition |
| abstract | The present invention discloses a kind of alkali method and carries aluminium and obtain the method for dealkalize red mud, comprising: (1) prepares raw material according to raw mix formula, and raw material comprise aluminum-containing raw material, sodium oxide presoma and magnesium oxide presoma, and optional calcium oxide presoma; (2) raw material are carried out roasting at 800-1300 DEG C, obtain sintered clinker; (3) sintered clinker is obtained red mud and dissolution fluid through stripping, solid-liquid separation; (4) dissolution fluid carried out desiliconization, after carbon divides, obtain aluminium hydroxide; (5) red mud is carried out dealkalize, obtain the dealkalize red mud containing Magnesium Silicate q-agent; Wherein, raw mix formula meets the mol ratio of its component oxide for ([MgO]+[CaO])/([SiO 2 ]+[TiO 2 ])=0.9-1.1. Also disclose the dealkalize red mud and application thereof that obtain by aforesaid method. The inventive method can keep higher aluminum oxide standard solubility rate, and carries aluminium added value height. |
