The production process within these factories is intricate and requires precise control over chemical reactions. First, the raw rutile ore is extracted from mines and then crushed into a fine powder. This powder undergoes a series of leaching processes to remove impurities. Afterward, it is subjected to the chlorination process, where it reacts with chlorine gas at high temperatures to produce titanium tetrachloride. This compound is then refined further through vapor deposition or oxidation to yield high-purity titanium dioxide.

To make up the batch of lithopone the solution containing the original 1050 pounds of barium sulphide and 856 pounds of titanium acid cake is added to sufiicient zinc sulphate solution of approximately 35 Baum at 60 Centigrade to completely precipitate all the BaS as zinc sulphide and barium sulphate so that the final precipitate contains a suspen-. sion of co-p'recipitated zinc sulphide barium sulphate intimately mixed with a suspension of titanium oxide. On the completion of the reaction, shown by the complete absence of either soluble zinc or barium in a filtered por-.
