METHOD FOR OBTAINING NON-MAGNETIC ORES FROM A SUSPENSION-LIKE MASS FLOW CONTAINING NON-MAGNETIC ORE PARTICLES

摘要

A method obtains non-magnetic ores from a suspension-like mass flow containing non-magnetic ore particles. The method involves mixing the mass flow with magnetic particles in a mixing device and forming ore particle-magnetic particle agglomerates, feeding the mass flow as a separator feed flow to a magnetic separator for separating the ore particle-magnetic particle agglomerates from the mass flow, forming a separator concentrate flow containing ore particle-magnetic particle agglomerates and a separator residual flow containing the remaining constituents of the mass flow, and separating the ore particles from the ore particle-magnetic particle agglomerates contained in the separator concentrate flow. At least one information indicating a measurement of the content of ore particles or magnetic particles in the separator feed flow and/or the separator concentrate flow and/or the separator residual flow is determined for determining an efficiency of at least one of the mixing apparatus and/or the magnetic separator.
