Abstract: Provided are a method for preparing an adsorbent from industrial vermiculite, an adsorbent and application thereof. The method comprises steps: flaking and de-polluting the raw industrial vermiculite ore to obtain industrial vermiculite fine flakes; grinding the industrial vermiculite fine flakes to obtain industrial vermiculite powder; mixing the industrial vermiculite powder with a binder and granulating it to obtain an industrial vermiculite granular; and post-treating the industrial vermiculite granular to obtain the adsorbent. The adsorbent is prepared by the method. Applications may include purification of benzene gases such as toluene, sewage treatment, horticulture, soil improvement and applications in agricultural carriers. The adsorbent of the disclosure has the advantages of high cation exchange capacity, large internal specific surface area, strong adsorption of toluene and lightweight porous, etc. Moreover, the preparation method of the disclosure is simple, green, low production cost and easy to be produced on a large scale.

Abstract: Provided are a method for processing titanium extraction slag and a carbon extraction and dechlorination tailing. The method comprises the following steps that a titanium extraction slag raw material is ground to obtain a treated material with a particle size being 0.3˜120 μm and d90≤90 μm; a first solvent and a treated material are mixed with a liquid-solid ratio of (3.5˜4.5): 1 L/kg, and a first capturing agent and a first foaming agent are added for mixing and then subjected to a primary flotation to obtain a floating product and a sinking product; and a second solvent is added into the floating product to adjust the liquid-solid ratio to (4˜5): 1 L/kg, a second capturing agent and a second foaming agent are added for mixing and then subjected to a secondary flotation to obtain a foam product; the foam product is filtered and dried to obtain a refined carbon, and the sinking product is filtered and dried to obtain the carbon extraction and dechlorination tailing, wherein the d90≤90 μm means that more than 90% of the powder in the treated material has a particle size of less than 90 μm. The method has the advantages that carbon in the titanium-extracted slag can be recycled, chlorine is removed, and the carbon extraction and dechlorination tailing can be used as a building material raw material.
