Abstract

Separation facilities ensuring flexible control over produced ore mass quality, with potential production of concentrates with high metal content are examined. The process solutions are justified to develop small gold ore deposits located far from processing factories, in the areas of the underdeveloped or missing energy infrastructure. A mobile processing facility carries out two-stage X-ray radiometric separation of sorted ore classes, with production of tailings, middlings and concentrate via float-and-sink separation. Middlings are treated on-the-spot by heap and trench leaching, and concentrate is shipped to a long-distance processing factory. Separate processing of different-grade mineral raw material enables high metal recovery at a reasonable cost.
