The safety of food-grade titanium dioxide, or E171, lies in its ultrafine particle size. These particles are too small to be absorbed by the human body, passing through the digestive system without causing harm. Extensive research has been conducted to confirm this, with studies showing no evidence of genotoxicity or carcinogenicity. However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluationsfood safe titanium dioxide.

    Rutile, the most common form of titanium dioxide, is a reddish-brown pigment with a high refractive index and excellent weathering resistance. It is mainly used in paints, coatings, plastics, and paper industries due to its ability to provide excellent whiteness, opacity, and UV protection. Rutile titanium dioxide is typically produced by the sulfate process, which involves the reaction of titanium ore with sulfuric acid to produce titanium sulfate. The resulting solution is then treated with ammonia to precipitate titanium hydroxide, which is subsequently calcined at high temperatures to obtain rutile titanium dioxide.

    At present, the domestic wet zinc smelting mainly adopts the roasting-leaching-electrowinning production process, and the zinc content in the acid leaching residue is generally 8-15%, some up to 20%, and the sulfur mass fraction is 6-12%, of which sulfuric acid The root mass fraction is 15-30%, mainly in the form of 0^0 4 (in this ammoniatic environment, the leaching rate of sulfate leaching in multiple stages can reach 70%). The zinc in the acid leaching residue is mainly in the form of ZnFe 2 0 4 . In order to recover these zinc, the treatment methods are currently available in the fire method and the wet method. The fire method is the rotary kiln evaporation method (Wilz method) and the fumigating furnace evaporation method. . The wet method has hot acid leaching or high temperature pressure leaching. The fire treatment process is long, the equipment maintenance is large, the investment is high, the working environment is poor, and a large amount of coal or metallurgical coking coal is consumed, which has low efficiency and large environmental pollution. Therefore, it is usually leached by hot acid or high-pressure leaching. These methods still have the disadvantages of: 1 consumption of a large amount of acid, low leaching rate, due to the large amount of calcium sulfate, calcium sulphate and other ultrafine particles to isolate the zinc oxide particles, resulting in Electrolytic zinc enterprises are difficult to leach in acid environment, and the second weak acid leaching is not meaningful because the recovery rate is too low. 2 If leached with strong acid, although ZnFe 2 0 4 is destroyed, the leaching rate is improved, but the iron leaching rate is also high (up to 60%). The pressure of iron removal is large, and more reagents are consumed. 3 High temperature and high pressure equipment is corroded. Serious, complicated equipment investment; 4 high operating costs, poor economic returns. 5 The last slag discharged is acid leaching residue, which brings new pollution to the environment. It has to be cured and landfilled, which not only pollutes the environment, but also wastes resources.
