Abstract

The invention aims to provides a method for determining titanium dioxide content in titanium concentrate. The method comprises the steps of (1) titanium concentrate sample preprocessing, (2) preparation of a dissolved sample of the titanium concentrate sample, (3) the titanium concentrate dissolved sample titration and (4) titanium dioxide content calculation. The detailed method comprises thesteps that the titanium dioxide content in the titanium concentrate is determined, and the titanium dioxide content determination is much important in determining the titanium concentrate raw materialquality and controlling the titanium dioxide production. It is due to the fact that partial titanium dioxide can be converted into an insoluble rutile form in the sample melting process of the titanium concentrate, acid is adopted to dissolve the sample, thereby easily leading to incomplete sample decomposition and a lower analysis result of the titanium dioxide. An ammonium ferric sulfate volumetric method is adopted to determine the titanium dioxide content in the titanium concentrate, alkaline reinforcer-sodium peroxide is adopted to melt the sample at a high temperature, so that the sample decomposition is more thorough, and it is more beneficial to extract Ti from the sample. According to the method, the analysis result of TiO2% is more accurate, and the production requirements are completely met.

Description

technical field [0001] The invention relates to the field of component analysis and testing of titanium ore, in particular to a method for determining the content of titanium dioxide in titanium concentrate. Background technique [0002] Titanium dioxide scientific name titanium dioxide (TiO 2 ), molecular weight: 79.88, is a kind of white inorganic pigment, has non-toxicity, best opacity, best whiteness and brightness, is considered to be a kind of white pigment with best performance in the world at present, is widely used in coating, Plastic, paper making, printing ink, chemical fiber, rubber, ceramics, cosmetics, food additives and pharmaceutical industries. Titanium dioxide has two main crystalline forms: Anatase, referred to as type A and rutile, referred to as type R. There are also two manufacturing methods of titanium dioxide: sulfuric acid method and chlorination method. The sulfuric acid method is to produce titanous sulfate through acidolysis reaction of ferroti...
