Process for the processing of mine waters

摘要

Process for the processing of iron and sulfate-containing mountain water leakage at the factory and mine effluents, whereinin a first process step the mountain water at the factory and mine effluents in a settling container is collected and are swirled with air and to accelerate the sedimentation the mine effluents mountain water leakage at the factory and a polymeric additive is added, wherein a mine effluents mountain water leakage at the factory and contained in the solids content of pyrite to fe₂O₃ and h₂So₃ oxidized, the polymeric additive together with the fe₂O₃ flocculates out and sedimented and the sediment is removed from,in a second process step, the remaining sulfate-containing water is passed into a reaction well, the sulfate content is determined and in the stoichiometric ratio for this purpose with an addition of calcium compounds such as calcium hydroxide and / or calcium oxide and / or calcium carbonate and / or calcium chloride or with an addition of barium compounds, such as barium oxide and / or barium hydroxide and / or barium carbonate and / or barium chloride is added, the dissolved ingredients to solid materials such as calcium sulfate or barium sulfate are reacted, and sedimentation,in a third method step, and – if the additives are no chloride compounds, the thus prepared mine leachate or mine waste collected or as utility water is diverted into a drainage receptacle 35, or if the additives are the compounds and – chloride-containing water and then cleaned is diverted into a drainage receptacle 35.
