Abstract:
1. A method for obtaining non-magnetic ores from a suspension mass flow containing non-magnetic ore particles, comprising: mixing the mass flow with magnetic particles in a mixing apparatus to form ore particle-magnetic particle agglomerates and produce a separator feed flow containing the ore particle-magnetic particle agglomerates; feeding the separator feed flow to a magnetic separator to separate the ore particle-magnetic particle agglomerates, to produce a separator concentrate flow having an enriched concentration of ore particle-magnetic particle agglomerates and to produce a separator residual flow containing remaining constituents of the separator feed flow; splitting the ore particles from the ore particle-magnetic particle agglomerates contained in the separator concentrate flow; determining first and second content information, the first content information specifying a content of ore particles or magnetic particles in a first stream, the second content information specifying a content of ore particles or magnetic particles in a second stream different from the first stream, the first and second streams being selected from the group consisting of the separator feed flow, the separator concentrate flow and the separator residual flow; comparing the first and second content information to produce a comparison result; and setting an operating parameter of the mixing apparatus or the magnetic separator based on the comparison result.
