Abstract
A method for magnetic ore separation and/or dressing is provided, in which metalliferous recoverable materials are separated from conveyed metalliferous ore rock. The method may include producing a pulp including metalliferous recoverable material, executing a hydrophobizing reaction of 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, separating the magnetizable agglomerates from the pulp, mixing separation products containing the agglomerates with a non-polar liquid insoluble in water and decomposing the agglomerates in the non-polar liquid into magnetizable material and recoverable material, separating the magnetizable material from the recoverable material, and removing moisture from the separation portion containing the recoverable material of the second separation stage to synthesize the recoverable material.
