Abstract

método de separação de partículas, método de remoção de partículas, aparelho para separar partículas hidrofóbicas e aparelho para a remoção de partículas hidrofóbicas a separação de partículas hidrofóbicas de uma mistura de partículas em um fluido é executada mediante a provisão de um leito fluidizado ( 18) como um mecanismo de contato relativamente não turbulento em uma célula de flotação que incorpora uma câmara de sedimentação (30) localizada imediatamente acima do leito fluidizado. partículas hidrofóbicas se ligam às bolhas no leito fluidizado 18 e ascendem para a interface (19) com a câmara de sedimentação (30) onde as partículas não hidrofóbicas (22) fluem sobre a virola (20) de uma pia interna e são removidas como refugos (21) . as partículas hidrofóbicas unidas às bolhas flutuam ascendentemente na câmara de sedimentação relativamente plácida ( 3 o) onde a gangue não desejada pode cair de volta na interface (19) . as bolhas formam uma camada de espuma na superfície superior da câmara de sedimentação, e fluem sobre a virola da pia (32) que suporta as partículas hidrofóbicas. uma operação do aparelho é mantida estável ao recircular o fluido da câmara de sedimentação (30) através da tubulação (40) e da bomba (41) para misturar com a nova carga que entra no duto (2).
