Abstract:
1. A method for magnetic ore separation and/or dressing, in which metalliferous recoverable materials are separated from conveyed metalliferous ore rock, comprising: producing a pulp comprising a liquid mixture comprising water and ground rock, the pulp including at least one metalliferous recoverable material, executing a hydrophobizing reaction of the at least one recoverable material in the pulp, synthesizing a hydrophobized, magnetizable material in liquid suspension and adding this suspension to the pulp, causing an agglomeration reaction between hydrophobized magnetizable material and hydrophobized recoverable material to form magnetizable agglomerates in the pulp, performing a first magnetic separation stage to separate the magnetizable agglomerates from the pulp, mixing one of the separation products of the first magnetic separation stage, containing the agglomerates, with a non-polar liquid insoluble in water and decomposing the agglomerates in the non-polar liquid into the basic components of magnetizable material and at least one recoverable material, performing a second magnetic separation stage to separate the magnetizable material from the at least one recoverable material, removing moisture from the separation portion containing the at least one recoverable material of the second separation stage to synthesize the at least one recoverable material.
