lithopone 28%-30% factory

The production process of titanium dioxide involves several stages, starting with the extraction of raw materials from mineral ores such as ilmenite, rutile, and anatase. These ores are then processed through various methods, including the sulfate and chloride processes, to produce high-purity titanium dioxide powder. The sulfate process involves treating the ore with sulfuric acid to extract titanium dioxide, while the chloride process uses chlorine gas to produce a purer form of the pigment.
