The invention relates to the technical field of fine chemicals, in particular to a method for producing liquid barium chloride with low-grade witherite ore powder. There are two production methods of barium chloride, one is the barite reduction method, and the other is the high-grade witherite mineral powder hydrochloric acid method. The barite reduction vulcanization process has high product purity, but the equipment investment is large and the environmental pollution is serious. Another method is to use high-grade witherite ore powder or add a small amount of low-grade witherite ore powder to produce barium chloride solution by leaching with hydrochloric acid, but the production cost of this method is relatively high. And fully produce barium chloride solution with low-grade witherite ore powder (content is about 68%), there is no report yet. The present invention completely uses low-grade witherite mineral powder (content is about 68%) to produce barium chloride solution, adopts the method for adjusting pH value by adding sodium hydroxide solution intermittently in multiple stages, removes Mg2+, Ca2+, Sr2+ respectively, and Ba2+ content loss Reduced to a minimum, the product meets quality standards.
