CL2021000363A1 Combinación de separación de portador magnético y una separación adicional para el procesamiento de minerales 未知

Combinación de separación de portador magnético y una separación adicional para el procesamiento de minerales
Abstract:
La presente invención se refiere a un proceso para concentrar partículas deseadas que comprende a) proporcionar una materia prima que contiene las partículas deseadas y un material no deseado; b) añadir partículas magnéticas hidrofóbicas a la materia prima; c) separar los aglomerados de la materia prima cargada; d) romper los aglomerados aislados; y e) separar las partículas magnéticas de la suspensión obtenida en la etapa d).
Abstract(English):

A process for concentrating desired particles containing a carrier-magnetic-separation with the following steps, providing a feedstock which contains the desired particles; adding hydrophobic magnetic particles to the feedstock which results in a loaded feedstock containing agglomerates of the magnetic particles and the desired particles or of the magnetic particles and the undesired material; separating the agglomerates from the loaded feedstock by a separation method which results in isolated agglomerates, breaking up the isolated agglomerates to obtain a suspension having magnetic particles in de-agglomerated form; and separating the magnetic particles from the suspension obtained in step d) by a separation method and provided that at least one separation method is a magnetic separation, and where the process has at least one further separation and where the further separation is s sorting, electric separation, screening, classification, gravity concentration, and flotation.
