Abstract

Una pluralidad de superficies de recoleccion para su uso en una suspension acuosa tiene un revestimiento polimerico para proporcionar una superficie adherente y adherente. El revestimiento de polimero tiene una sustancia quimica que hace que la superficie sea hidrofobica para atraer particulas minerales hidrofobicas o hidrofobizadas en la suspension. El sustrato puede tomar la forma de una banda transportadora, una microesfera, una malla, un impulsor, un filtro o una superficie plana. El sustrato tambien puede ser una espuma de celulas abiertas. Se hace que las superficies de recoleccion que tienen las particulas minerales unidas sobre ellas interactuen con dioxido de carbono liquido y supercritico, de modo que las particulas minerales se pueden eliminar de las superficies de recoleccion.
