Dissolution behavior of light rare earth sulfates in magnesium sulfate and magnesium chloride solutions

Key Points

• Dissolution behavior is influenced by ionic strength and temperature, impacting the solubility of rare earth sulfates.
• A significant decrease in precipitation occurs with increased magnesium sulfate concentration, demonstrating its potential role in enhanced solubility.
• Experimental analysis using various concentrations assesses the thermodynamic properties of dissolution in magnesium chloride solutions.
• Understanding this dissolution behavior may enable more efficient resource recovery methods for rare earth elements.
