Abstract

The invention relates to the field of chemical industry, and particularly to a method and a device for extracting barium and barium salt from ore. The method comprises the steps of: washing the ore; roasting the washed ore, obtaining barium sulfide; processing the barium sulfide to obtain barium salt, wherein the barium salt includes barium sulfate and / or barium sulfide and / or barium carbonate; and processing the barium carbonate to obtain barium. The device comprises a washing device for washing the ore; a roasting device for roasting the washed ore so as to obtain barium sulfide; a first reacting device for processing the barium sulfide so as to obtain barium salt, wherein the barium salt includes barium sulfate and / or barium sulfide and / or barium carbonate; and a second reacting devicefor processing the barium carbonate so as to obtain barium. The method and the device for extracting barium and barium salt from the ore provided by the invention can make full use of ore resources to obtain barium and barium salt.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method and a device for extracting barium and barium salt from ore. Background technique [0002] Barium series products are led by metal barium, barium series products are barium carbonate, precipitated barium sulfate and the by-products of "three wastes" treatment sodium sulfide, calcium phosphate compound fertilizer, sodium carbonate, barium chloride, barium sulfide, barium hydroxide and oxide barium etc. Barium series products are currently produced in single-phase form in China, that is, only one of sodium sulfide, calcium phosphate compound fertilizer, sodium carbonate, barium chloride, barium sulfide, barium hydroxide and barium oxide is produced or processed. Waste of mineral resources, can not comprehensively develop and utilize the shortcomings of resources. Contents of the invention [0003] The invention provides a method and device for extracting barium and bar...
