ABSTRACT:
The settling of finely-divided solids that are in suspension in an aqueous medium due to the presence of a colloidal argillaceous mineral is enhanced by adding a small but effective amount of an organic peroxide to the suspension. This invention is especially useful for treating aqueous suspensions of ultrafine clay and other materials resulting from the hydraulic concentration of an ore material, such as phosphate slimes.
