Abstract
This invention refers to chemical technology of inorganic products and can be used, in particular, for obtaining barite compounds including pharmacopoeia barium sulphate and also high percent barite concentrate. This invention ensures simplification in technology for obtaining barium sulphate of high purity from low percent barite concentrate with simultaneous producing barite concentrate with high content of the main product. The process for the production of high purity barium sulphate comprises the steps of sintering low percent barite concentrate in a 5:1 ratio within the temperature range of 700-8000C, leaching obtained product boiled up to 80-900C by 2-5 percent sodium carbonate solution and subsequent treating leach residue by 10-20 percent sulphuric acid solution. 1 ind., cl.
