Abstract
La invencion se refiere a un metodo para mejorar el rendimiento de la filtracion al separar solidos de liquidos en una dispersion acuosa que comprende una fase solida y una fase liquida en un proceso de dos etapas que tiene una etapa de separacion fisica y una etapa de filtracion que comprende la adicion de al menos un activador coadyuvante de filtracion y al menos un polimero sintetico a la dispersion acuosa durante y/o antes de la etapa de separacion fisica que resulta en el concentrado y la filtracion del concentrado. El metodo puede ser aplicado en operaciones de mineria para la deshidratacion de lodos mineros. Ademas, una composicion aplicada en dicho metodo que comprende al menos un activador coadyuvante de filtracion y al menos un polimero sintetico. El activador coadyuvante de filtracion comprende polimeros naturales, polimeros seminaturales, coagulantes y combinaciones de ellosThe invention relates to a method for improving filtration performance by separating solids from liquids in an aqueous dispersion comprising a solid phase and a liquid phase in a two-stage process having a physical separation stage and a filtration stage. comprising the addition of at least one filter aid activator and at least one synthetic polymer to the aqueous dispersion during and / or prior to the physical separation step that results in concentrate and filtration of the concentrate. The method can be applied in mining operations for the dewatering of mining sludge. Furthermore, a composition applied in said method comprising at least one filter aid activator and at least one synthetic polymer. The filter aid activator comprises natural polymers, semi-natural polymers, coagulants and combinations thereof.
