METHOD FOR SEPARATING A DEFINED MINERAL PHASE OF VALUE FROM A GROUND ORE

摘要

The invention relates to a method for separating a defined mineral phase of value (2) from a ground ore (4) having several chemical phases and being present in a heterogeneous particle size distribution, comprising the following steps: - classifying (6) the ore according to a defined particle diameter into at least two fractions, a first fraction (8) having particles essentially larger than the defined particle diameter and a second fraction (10) comprising particles essentially smaller than the defined particle diameter, and the defined mineral particles of value (2) being present in both fractions (8, 10), - floating (11) the first fraction having the greater particle diameters and selecting the defined mineral particles of value (2) in a flotation concentrate (12), - selectively admixing the defined mineral particles of value (2) in the fraction (10) having the smaller particle diameters with magnetizable particles (14), - applying a magnetic separation process to the second fraction (10) having smaller particle diameters and separating a concentrate (16) with an enrichment of the defined mineral phase of value (2).
