Abstract: BACKGROUND: Currently in the country there is no production of potassium carbonates, which, as a rule, they are purchased in the CIS countries. At the same time, there has explored sufficient reserves of potassium-containing raw materials, which, according to technological, economic and, most importantly, rational utilization levels, will provide an opportunity to get their own potassium carbonate to ensure internal and external consumption markets. In this regard, the development of a method of producing potash based on local raw materials is currently actual. RESULTS: The process of obtaining potassium bicarbonate by the amine method has been studied for the first time. The optimal process parameters were established: ΔP = 2 atm, duration – 45 min. CONCLUSION: The study found that the resulting potassium bicarbonate precipitates quickly from the suspension and is easily filtered, which allows us to recommend the use of existing standard thickeners and filtering plants with a minimum working surface.
