Alkaline Pressure Digestion Ion Exchange Method
The alkaline pressure digestion method has the characteristics of long service life, low cost, strong production capacity and high production efficiency, and the leaching agent is sodium hydroxide. At present, more than 80% of the domestic tungsten ore raw material decomposition adopts this technology. This technology has strong applicability to raw materials, so it has become a general technology for processing various tungsten ores.
The ion exchange method utilizes the difference in affinity between each anion group and 201*7 anion resin to effectively separate tungsten from impurities, and obtain pure ammonium tungstate solution through adsorption and desorption. At present, the vast majority of domestic tungsten smelting enterprises use the ion exchange method.
