r6618 tio2 factory

The factory's production process is a testament to precision and optimization. Raw materials, primarily ilmenite, rutile, and anatase ores, undergo a rigorous refining process that includes crushing, leaching, and solvent extraction methods. These steps ensure the purity and consistency required for high-quality pigments. Following this, gaseous chlorination converts the refined ore into titanium tetrachloride, setting the stage for the final synthesis of titanium dioxide through the oxidation of titanium tetrachloride in a heated environment.

 At present, Lide powder is mainly produced in China. Most of the domestic Lide powder production is still using traditional methods. The main raw materials are zinc oxide, sulfuric acid and barium sulfide (barite and coal are produced by high temperature reduction). Zinc 45% ~ 70%. The traditional method for producing the Liede powder process is to use zinc bakelite containing more than 45% zinc as a raw material to be leached with sulfuric acid to obtain a crude zinc sulfate solution, and then to remove iron by potassium permanganate, and then replace the heavy metal with zinc powder and filter to obtain zinc sulfate. The refined liquid is further subjected to metathesis reaction, pressure filtration, calcination, rinsing, drying, and pulverization with strontium sulfide to obtain a series of different types of lindose powder containing zinc sulfide of 30% or more. The whole process is carried out in an acidic (ra<7) environment, which consumes a large amount of sulfuric acid. The sulfuric acid has strong corrosiveness and requires high production equipment. The final discharged slag is acidic slag, which brings new pollution to the environment. High requirements, high production costs, and poor quality of the products obtained.
