Abstract
In a method for separating rich ore particles from agglomerates which contain said rich ore particles and magnetizable particles attached thereto, especially Fe3O4, in which agglomerates of the rich ore particle and the magnetizable particle are bonded by organic molecular chains, the agglomerates are contained in a suspension containing a carrier fluid and are broken up by an input of mechanical energy so that an agent contained in the suspension and decomposing the exposed, hydrophobic molecular chains can act upon the molecular chains. The Fe-containing oxide components are separated from the suspension in a magnetic separation process.
