sufiicient sulphuric acid to extract up to 95 per cent or more, of the titanium oxide prescut. This extraction is carried on so that the resulting product, after the addition of the required amount of sulphuric acid, is in the form of a dry powdered .mass, in which approximately 95 per cent of the titanium is in a soluble form. Th dry powdered mass is thenextractedin suitable leaching tanks with water, whereby a solution of approximately 70 grams of sulphuric acid and 100 grams of titanium oxide to the liter, is obtained.

The natural barite containing more than 95% of barium sulfate is mixed with anthracite in a ratio of 3:1 (mass), and is pulverized to a diameter of about 2 cm or less to enter a reduction furnace, and the front stage of the furnace temperature is controlled by 1000 to 1200 ° C, and the latter stage is 500 to 600 ° C, the reduction furnace rotates at a speed of 80s per revolution, the reaction conversion rate is 80% to 90%, the obtained barium sulfide enters the leaching device, the control temperature is above 65 ° C, and the content of barium sulfide is 701%, and then enters the clarification. The barrel is clarified and then added with zinc sulfate to control the zinc sulfate content to be greater than 28%, and the pH is 8-9, and a mixture of barium sulfate and zinc sulfide having a density of
