METHOD FOR THE RECOVERY OF POTASSIUM FROM RED MUD

METHOD FOR THE RECOVERY OF POTASSIUM FROM RED MUD

Red mud is dissolved in ferric sulfate, aluminum sulfate or their hydrates, or optionally a portion of red mud is dissolved in 1-100% (preferably, 20-30%) sulfuric acid. The insoluble content in the solution is filtered. The solution is then crystallized and heat-treated at 50-1000[deg]C (preferably...

description Red mud is dissolved in ferric sulfate, aluminum sulfate or their hydrates, or optionally a portion of red mud is dissolved in 1-100% (preferably, 20-30%) sulfuric acid. The insoluble content in the solution is filtered. The solution is then crystallized and heat-treated at 50-1000[deg]C (preferably, 100-200[deg]C) in presence of mixture of ferric sulfate and aluminum sulfate as sulfating agent for 0.1-10 hours. Then, sodium content is extracted from the obtained reaction mixture by leaching with water.
