Abstract | The present invention relates to methods for dewatering tailings and systems for performing same. In certain aspects, the invention relates to methods of producing a dewatered tailings residue or a stackable tailings residue, comprising subjecting tailings to hydrocyclonic separation to produce one or more partially dewatered underflows and a final water-rich overflow; separating the final water-rich overflow, by centrifuging, into a recovered water stream and a low-water residue; and mixing together the low-water residue and at least part of the one or more partially dewatered underflows to produce a dewatered tailings residue or a stackable tailings residue.
La presente invención se refiere a métodos para deshidratar relaves y sistemas para realizar esto. En ciertos aspectos, la invención se refiere a métodos para producir un residuo de relaves deshidratado o un residuo de relaves apilable, que comprende someter los relaves a separación hidrociclónica para producir uno o más subdesbordamientos parcialmente deshidratados y un desbordamiento final rico en agua; separar el desbordamiento final rico en agua, por centrifugación, en una corriente de agua recuperada y un residuo pobre en agua; y mezclar entre sí el residuo pobre en agua y al menos parte de uno o más subdesbordamientos parcialmente deshidratados para producir un residuo de relaves deshidratado o un residuo de relaves apilable. |
