Problems solved by technology

It contains a considerable amount of acid-soluble barium, which will cause waste of resources if not recycled
Judging from the current papers and patents on the production of barium chloride by the barium slag method, it is only a general theoretical discussion, and there is no separation of impurities and particles brought by the slag, such as calcium, magnesium, sulfite, thiosulfate, etc. Propose methods that pose difficulties to the feasibility of putting into production implementation

Abstract

The invention discloses a method for producing barium chloride through barium residues of barium sulfate. The method comprises the following steps of: S100, grinding the barium residues with water or a dilute barium chloride solution into slurry through a ball mill; S200, adding hydrochloric acid to the obtained slurry, performing a reaction so as to obtain a barium chloride mixed solution, and controlling the PH value of a terminal point to be 6.5-7.5; S300, performing filtering separation on the obtained mixed solution, abandoning residues, reusing the abandoned residues, enabling washing water to be used for the ball mill, and enabling a mixed clear solution to be used for a next working procedure; and S400, adding hydrogen peroxide to the solution obtained in the S300, and performing oxidation so that vulcanized sulfate ions and sulfinic acid ions are converted into sulfate ions to be removed, and bivalent iron ions are oxidized into ferric ions. According to the method disclosed by the invention, the barium residues are effectively utilized, and the purity of the prepared barium chloride is high.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a barium chloride production method. Background technique [0002] At present, the barium slag in the domestic barium salt industry is basically stored on site, or buried, and partially made into bricks and cement. It contains a considerable amount of acid-soluble barium, which will cause waste of resources if not recycled. Judging from the current papers and patents on the production of barium chloride by the barium slag method, it is only a general theoretical discussion, and there is no separation of impurities and particles brought by the slag, such as calcium, magnesium, sulfite, thiosulfate, etc. The proposed method brings difficulties to the feasibility of putting it into production. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides a method for producing barium chloride, comprising the following steps: S100: use ...
