Abstract
Abstract—A technology is proposed to process ancylite-containing raw materials—ore or concentrate. The technology is based on their decomposition with 1 wt % HCl in the presence of a sulfonic cation-exchange resin in hydrogen form at a temperature of 20–50°C. The process flow diagram is given. The technology is characterized by low consumption of reagents and the absence of liquid waste.
