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
