Abstract:
1. A process for separating a material from a mixture, the process comprising: (A) contacting a mixture comprising a first material and a second material with a magnetic particle in the presence of a dispersion medium, thereby agglomerating the first material and the magnetic particle and obtaining a dispersion; (B) optionally, adding a second dispersion medium to the dispersion obtained in (A); (C) separating the agglomerate from (A) or (B) from the dispersion by applying a magnetic field; and (D) dissociating the agglomerate from (C), to obtain the first material and the magnetic particle separately, wherein: an energy input of at least 10 kW/m the first material is coal or at least one hydrophobic metal compound selected from the group consisting of a sulfidic ore, an oxidic-comprising ore, and a carbonate-comprising ore; and the second material is a hydrophilic metal compound selected from the group consisting of an oxidic and a hydroxidic metal compound.
