Solid-liquid separation is an operation to separate the solid and liquid in the ore pulp or suspension. In the chemical mineral processing, the ore pulp and chemical precipitation suspension leached often require solid-liquid separation to obtain clear solution and solid products to meet the requirements of subsequent processes.
Separation occurs when the minerals are soaked in a chemical solution, causing the materials to aggregate based on whether they are hydrophobic (water-repellant) or hydrophilic (water-attracting). Froth flotation uses …
The present work investigated the chemical speciation of the UO 2 2+ (uranyl) in the presence of sulfate using density functional calculations (DFT) of the chemical species and their interaction with the resins to elucidate such counter-intuitive mechanism. It was demonstrated the great selectivity and loading capacity towards …
