Primary grind and rougher recovery relationship of southwest deposit of Oyu Tolgoi ore: Phase 4B high-grade gold

Abstract

The objective of this study was to investigate the effect of different primary grind sizes for the Cu (copper) and Fe (iron) recovery of the Phase 4B high-grade gold ore, which is from the southwestern deposit of the Oyu Tolgoi deposit. A series of nine rougher flotation tests have been completed to assess the primary grind size at the Mineral Processing laboratory of German-Mongolian Institute for Resources and Technology
