Suppliers play a crucial role in transforming these raw materials into usable titanium dioxide. They employ specialized extraction techniques such as the Becher process for ilmenite or the sulfate process for rutile and anatase, which involve chemically treating the ore to produce titanium dioxide. In the sulfate process, for example, the ore is treated with sulfuric acid to form titanyl sulfate, which is then calcined to yield titanium dioxide.

The primary concern surrounding the use of TiO2 in food is its potential to be inhaled or ingested. While TiO2 is generally recognized as safe for consumption by the US Food and Drug Administration (FDA), there are some studies that suggest that it may have adverse effects on human health when consumed in large quantities over a long period of time. These studies have linked TiO2 to respiratory problems, such as inflammation and irritation, as well as potential carcinogenic effects.

  •  The zinc content in the electrolytic zinc acid leaching residue in the leaching step is 5% to 35%. In the purification step, after the primary immersion liquid is added with ammonium persulfate for one oxidation, a polyacrylamide coagulant is added before the filtration separation. It is used for flocculation to produce arsenic and iron coprecipitation to remove harmful elements.
