The Kinetic Aspects of the Dissolution of Slightly Soluble Lanthanoid Carbonates

Tatiana Litvinova et al.

Summary: The complex use of mineral raw materials is significant in many industries, especially in the rare earth industry where a comprehensive solution has not yet been developed. This study examines the kinetics of the dissolution process of poorly soluble lanthanide compounds, showing the dependence of lanthanide extraction on variables such as temperature, concentration of complexing agent, and mixing intensity. The results provide insight into the activation energy and reaction orders, with the prospect of creating a mathematical model for extracting a rare earth metal by the carbonate alkaline method.

The adsorption mechanism of synergic reagents and its effect on apatite flotation in oleamide-sodium dodecyl benzene sulfonate (SDBS) system

Zhan Ding et al.

Summary: The use of synergistic reagents significantly improves the flotation efficiency of phosphate ore. Experimental results showed that adjusting the dosage and molar ratio of oleamide and SDBS in the mixed collector system can enhance the recovery rate of apatite. The presence of SDBS was found to strengthen the adsorption of oleamide, leading to changes in the chemical state of the apatite surface and improving the flotation effect.
