Method for preparing auxiliary cementing material from titanium extraction slag, and auxiliary cementing material
The invention provides a method for preparing an auxiliary cementing material from extracted titanium slag, and the auxiliary cementing material. The method comprises the steps that the extracted titanium slag is washed with water till soluble chloride ions in the extracted titanium slag are completely dissolved out to obtain first filter residues and first filtrate, wherein the first filtrate mainly comprises calcium chloride and magnesium chloride; the first filter residues are dried and then ground to obtain powder with the first particle size; the powder with the first particle size is continuously washed with water to reduce the content of chloride ions in the powder to 2/10000 or below, and filtering is performed to obtain a second filter residue and a second filtrate; and the second filter residues are dried and mechanically activated to obtain second-particle-size powder, wherein the second-particle-size powder can be used as an auxiliary cementing material. The method has the advantages that chloride ions in the titanium extraction slag are removed through water leaching, secondary water leaching is carried out by means of the characteristic that filter residues obtained after water leaching do not absorb moisture, residual chloride ions are fully removed, the super-active superfine slag powder with the high activity reaching up to the S105 level or above is prepared, energy is saved, environment friendliness is achieved, and the added value of products is increased.
本发明提供了一种提钛渣制备辅助胶凝材料的方法以及一种辅助胶凝材料，所述方法包括步骤：将提钛渣水洗至其中可溶性氯离子完全溶出，得到第一滤渣和第一滤液，所述第一滤液中主要成分为氯化钙和氯化镁；将所述第一滤渣干燥后粉磨得到第一粒径粉体；将所述第一粒径粉体继续进行水洗使其中氯离子含量降至万分之二以下，过滤得到第二滤渣和第二滤液；将所述第二滤渣烘干并机械活化得到第二粒径粉体，所述第二粒径粉体即可作为辅助胶凝材料使用。本发明具有采用水浸去除提钛渣中的氯离子，借助水浸后滤渣不吸湿的特点，进行二次水浸，充分去除残留的氯离子、制得高活性活性高达S105级以上的超活性类矿渣微粉、节能环保、提高产品附加值等优点。
