Abstract
The invention discloses a method for preparing barium sulfate and co-producing sodium chloride. The method is that industrial products containing barium chloride and industrial products containing sodium sulfate react chemically with each other according to the mass ratio of 1:0.38-0.66 of pure barium chloride to pure sodium sulfate to obtain mixture of barium sulfate sediment and sodium chloride solution; the mixture is filtered to obtain a barium sulfate filter cake and sodium chloride filter solution; the barium sulfate filter cake is washed, dried, crushed and packaged to obtain barium sulfate products; and the sodium chloride filter solution is distilled under reduced pressure to obtain sodium chloride products. The invention has the advantages that the process of the method for preparing barium sulfate is simple, rapid and clear, especially when industrial barium chloride and sodium sulfate are used for producing barium sulfate, the production technology and the device are simple, the yield is extremely high and the benefit is very high.
Description
Technical field
The present invention relates to chemical filler barium sulfate preparation method, particularly, relate to a kind of method for preparing barium sulfate and co-producing sodium chloride.
Background technology
The method of producing process white is a lot, mainly based on barium ore production.As number of patent application is 200680047426.6, and denomination of invention is to have disclosed in the patent of barium sulfate product from the naturally occurring barite deposit of barium sulfate-containing crystal and the gangue material method that is equipped with barium sulfate product made of stones.And for example number of patent application is 200610167686, denomination of invention is for preparing the method for barium sulfate and zinc sulfate, this patent has disclosed utilizes barite and zinc-containing ores to be main raw material, by the black wood charcoal raw material of Containing Sulfur barium more than 50% with barite and coal mixed calcining system, leach clarifying sulfuration shellfish solution, with the reaction of barium sulfide solution and saltcake, reaction product is separated through press filtration again, and is dry, grind and make barium sulfate product.But the production productive rate of this method is lower, and the material volume of traffic is a lot, causes production unit complicated and huge.Thereby increased the production cost of barium sulfate greatly.
In addition, bariumchloride can make by single step reaction with barium carbonate and hydrochloric acid, has certain toxicity, be mainly used in the reagent that performs an analysis, dewatering agent, the system barium salt, and be used for industry such as electronics, instrument, metallurgy, price is very cheap, bariumchloride is used to prepare industrial barium sulfate, has great marketable value.
