TREATMENT OF CLAY SLIMES A process for dewatering slimes produced in mining and mineral processing operations whereby wet oxidation at 150-320.degree.C renders the solids rapidly settleable. Sufficient oxygen is supplied to meet or exceed oxygen demand. Inorganic solids in the oxidized product are separated and optionally further dewatered to a friable solid. Clarified water is recycled to the mining, mineral processing or other operations, or treated further, or discharged to the environment. Steam resulting from the wet oxidation is utilized in the mining or mineral processing operations. |
