A process of forming a second aqueous suspension of solid particles by gravity sedimentation of a first aqueous suspension of solid particles in a vessel is provided. The process comprises the steps of, adding at least one organic polymeric flocculant to the first aqueous suspension, thereby forming a suspension of flocculated solids, which flocculated solids settle to form a bed of consolidated solids, introducing an agent to form the second aqueous suspension, where the second aqueous suspension is of higher solids content than the first aqueous suspension, and where the agent is a free radical agent or an oxidising agent. |
