The natural barite containing more than 95% of Barium Sulphate and anthracite are mixed in a ratio of 3: 1 (mass), and destroyed to a diameter of less than about 2 cm into the recovery furnace. The temperature of the furnace is controlled to be 1000 to 1200 ° C in the first stage and 500 to 1200 in the latter stage. At 600 ℃, the recovery furnace rolls at a speed of 80s per revolution, and the response conversion rate is 80% ~ 90%. The prepared barium sulfide enters the extractor, the temperature is controlled above 65 ° C, and the barium sulfide content is 701%. Clean the barrel, add zinc sulfate reaction after clearing it, manipulate the zinc sulfate content to be greater than 28%, pH = 8 ~ 9, and obtain a mixture of Barium Sulphate and zinc sulfide with a density of 1.296 ~ 1.357 g / cm3.

The reaction liquid was filtered through a plate and frame to obtain a filter cake-like powder with a moisture content of not more than 45%, which was baked in a dry roasting furnace to change the crystal form of the powder, and then washed with sulfuric acid at 80 ° C. The end is washed with water, reinforced toner, filter press, dry and ground. The calcined product prepared by the ordinary zinc barium white production method is made into a slurry through beating, and then surface treated with sodium silicate, aluminum sulfate or sodium aluminate and a surfactant in turn, and then filtered, washed, dried, and destroyed. can.
