Abstract
The invention provides a method for preparing barium sulfate by recycling waste barium mud. The waste barium mud on the bottom of alkali solution storage tank and alkali solution clarifying tank in acompounding workshop is used as a raw material, so that the problems of space occupation and various pollutions to environment caused by the accumulated waste barium mud can be solved; the waste barium mud and coke dust can be calcined for regenerating barium sulfide which can be used as the raw material for producing barium sulfate; mass percent of barium sulfate in waste barium mud reaches up to96% or above, so that barium sulfide black ash with purity reaching up to 85% can be acquired through the reaction of waste barium mud and high-quality coke dust, and the barium sulfide content of the barium sulfide black ash is about 30% higher than that of the barium sulfide black ash acquired by calcining barite; according to the invention, waste barium mud is recycled, waste is turned into wealth and the method is economical and environment-friendly, so that a new method is supplied for solving the problem of solid waste emission in the industry of barium salt production and the production cost of enterprises can be greatly lowered.
