Gangue rejection from ores

A process for recovering value metals from ore comprising rock, including the steps of preselection of a grade of ore to be microwaved to form an ore stream; subjecting the ore stream to microwave energy to partially fracture rocks in the stream and form a partially fractured ore stream; crushing th...

More Information
Summary:A process for recovering value metals from ore comprising rock, including the steps of preselection of a grade of ore to be microwaved to form an ore stream; subjecting the ore stream to microwave energy to partially fracture rocks in the stream and form a partially fractured ore stream; crushing the partially fractured ore stream to preferentially fracture the pre-weakened ore, to form a crushed ore stream; and Screening the crushed ore stream to form a fines fraction ore stream for further processing; and a gangue fraction that may justify further processing.
