The invention describes a method for concentrating an aqueous suspension of solid particles, comprising the steps of adding at least one organic polymer flocculant to the suspension, thereby forming flocculated solid particles, where flocculated solid particles provide the ability to form a layer of solid particles and, therefore, to form a more concentrated suspension, which includes adding an effective amount of an agent that is selected from the group including free radical agents, o isliteli, enzymes, radiation, wherein the agent is introduced into the suspension prior to or substantially simultaneously with the addition of an organic polymeric flocculant and / or an organic polymeric flocculant is added to the slurry in the vessel and the slurry in the same vessel administered agent. This method is particularly suitable for separating solids and liquids, where flocculated solids are allowed to precipitate by sedimentation in a gravity concentrator. |
