Abstract

The invention discloses a multi-element flocculation-sedimentation agent for titanium-rich material acidolysis titanium liquid and its preparation and use methods, belonging to the field of solid-liquid separation. The technical problem to be solved by the present invention is that the flocculation particles of acid-lysis titanium-rich liquid with high concentration and high viscosity are small, have many colloids, and light specific gravity, which makes it difficult to flocculate and settle, and it is difficult to filter the settled sludge. Provided is a multi-element flocculation-settling agent for acid-lysis titanium solution rich in titanium. Multi-component flocculation and sedimentation agent for acidolysis titanium liquid rich in titanium, characterized in that it contains the following components by mass: flocculant: 0.5-3.0 parts, sedimentation carrier: 0.2-2.0 parts, auxiliary agent: 0.2-2.0 parts, water: 97.0-99.5 parts, and the total mass parts of flocculant and water are 100 parts. The clarified titanium solution obtained by using the multi-component flocculation-sedimentation agent for acidolysis of titanium solution with titanium-rich material of the present invention has fast settling, good filtration performance, and easy separation of deposited sludge, which is worthy of popularization and application.

Description

Technical field[0001]The present invention is belonging to the field of solid-liquid separation, and more particularly to a polyfricin-rich acid-resolved titanium solution multi-cell flocculation and preparation, method thereof.Background technique[0002]The acid-rich material prepared by hydrochloric acid is low, the impurity content is low, the acid soluble effect is good, and is a high-quality novel sulfuric acid pattern titanium white production raw material. Preparation titanium powder in sulfuric acid, the main processes are as follows: titanium-rich acid solution, ripening, dissolving, flocculation, clarification, solid - liquid separation, hydrolysis, one-time washing, bleaching, rinsing, salt treatment, calcined powder.[0003]The acid-soluble flavored material has a substance structure of the rutile prototype, which can be decomposed by concentrated sulfuric acid under certain conditions, to obtain a total titanium concentration, low iron and titanium ratio, viscosity, and ra...
