Coagulation/flocculation processes in dewatering of the flotation tailing slurries
Original language description
Flotation is widely used to clean fine coal particles by separating them from clay, silt, shale and other ash producing matter using air bubble. After flotation either the coal or tailings slurries must be dewatered for practical and economic advantages.The paper describes possibilities in dewatering of flotation tailing slurries, resulting from coal flotation in the coal preparation at the Paskov Mine (Czech Republic). In experiments were used coagulants: aluminium chlorohydrate (ACH) and polyaluminium chloride (PACl). Relation between tailings and addition of coagulant was characterized by zeta-potential. Temperature, turbidity, pH values and residual concentrations of aluminium were measured. The best results were achieved using by aluminium chlorohydrate. It accelerates the sedimentation process and the process water can be re-used.
