Abstract
Red oxide of iron, in a form suitable for use as a pigment, is obtained by roasting in air a mixture of ferrous chloride with excess of barium carbonate. A solution of ferrous chloride, for example galvanizer's waste pickle, neutralized, is mixed with witherite, which is ground so that it passes through a 30-mesh sieve, but is retained by one of 150-mesh. The witherite is present in an excess of from 50 to 100 per cent over the theoretical quantity. The solution is evaporated to dryness, and the product roasted at 300 DEG C. until the reaction is complete. The mass is treated with water, which dissolves the barium chloride, and forms a suspension of iron oxide, from which the unchanged witherite quickly settles. The oxide is filtered, washed, and dried, and barium chloride obtained from the filtrate by evaporation. The process may be modified by adding to the original mixture a finely-divided iron compound, which is decomposed under the conditions of the process. Hydrated ferric oxide, ferrous carbonate, and iron pyrites are suitable compounds. Two examples of the working of the process are given.
