The invention discloses a method for preparing titanium white by using acid waste water and pretreated titanium ore and belongs to the technical field of titanium ore production. The method comprises the following steps: before performing an acidolysis reaction on ground titanium ore, pretreating the ground titanium ore to remove partial impurities in the titanium ore; after the pretreatment is completed, performing solid-liquid separation; performing a de-acidolysis process on a solid phase (the titanium ore from which the impurities are removed); and after mixing a part of a liquid phase and the acid waste water, continuing to pretreat the titanium ore and delivering the remaining liquid phase to a sewage treatment station. After the titanium ore is treated by the method, impurities, such as about 80 percent of phosphorus, 50 percent of chromium and 50 percent of vanadium are removed, so that the quality of the titanium white is enhanced and partial acid amount during the acidolysisand ...

The recycling of diluted waste acid produced in the production process of sulfate process titanium dioxide is a bottleneck limiting the development of the sulfate process titanium dioxide. In addition, manufacturers of sulfate process titanium dioxide usually have sulfate acid production devices due to the need of a large amount sulfate acid. The invention relates to a method and a device for producing concentrated sulfuric acid by recycling waste acid from sulfate process titanium dioxide production. The method comprises the following steps: firstly, performing the pre-concentration of the diluted sulfate acid; secondly, removing most impurities carried by the diluted sulfate acid through settlement; and finally, using the sulfate acid subjected to pre-concentration and impurity removal to replace make up water of a sulfate production system, adding the sulfate acid into a sulfate circulating tank of a sulfate acid absorption tower to produce concentrated sulfate acid after sulfate acid ...

The invention discloses a preparation method of high-whiteness light-resistance rutile type titanium dioxide substrate. The preparation method includes steps of primary washing of metatitanic acid, preparation of metatitanic acid sizing, bleaching of metatitanic acid sizing, secondary washing of metatitanic acid, salt treating, roasting and smashing. In the bleaching of metatitanic acid sizing, 5wt% of rutile titanium dioxide roasted seed crystal and 0.2wt% of Ti3 and solution are added into the sizing. In the step of salt treating, potassium compound, phosphorous compound, aluminum compound and stibium oxide are added into the secondarily-washed metatitanic acid. By adding aluminum salt content, aluminum salt enters crystal lattice during growth of titanium dioxide crystal, light resistance performance of titanium dioxide pigment is substantially improved, and the yellowish problem caused by increment of aluminum slat content can be eliminated by adding antimonic salt, so that whiteness ...

The invention provides a method of using TiCl4 to prepare a high-activity double-effect crystal seed and control titanium dioxide particle size. Specifically, the method employs TiCl4 as a raw material, a precipitate is prepared through a certain proportion and rapid neutralization of a dilute base solution, the precipitate is subjected to peptizing, curing and quenching and then is adjusted to have a proper pH value, then soluble salt compositions are removed through washing, so that the high-activity double-effect crystal seed, which is applied to hydrolysis process and calcining process of production of sulfuric-acid-process titanium dioxide, is prepared. The prepared crystal seed is uniform in particle size and high in activity, and also during application of hydrolysis of a titanium solution, by adjusting the addition amount of the seed crystal and cooperating with addition of a proper salt treating agent and control on calcining intensity, rutile type titanium dioxide with different ...

Принадлежит:

A disclosed method for removing iron from a titanium dioxide concentrated acid solution comprises the following steps: (1) collecting the titanium dioxide concentrated sulfuric acid solution with the mass percentage of 45%-55% into a reaction tank; (2) adding an oxidant and a crystal seed into the reaction tank and performing oxidation, crystallization and curing; and (3) performing solid-liquid separation on the slurry obtained in the step (2), and using the separated liquid phase for wet-process phosphoric acid production. The method has the iron-removing rate of 65% or more, helps to effectively reduce the iron content of the titanium dioxide concentrated acid solution and improve the product quality of a phosphate salt, further optimizes sulfur-phosphor-titanium industrial chain and greatly reduces the production cost of phosphorus chemical industry and titanium chemical industry, and is substantial in economic benefit. The method has no waste and byproduct discharge in the whole process ...
