Ore sorting: the road to optimizing your operation
Sensorbased ore particle sorting can be used to preconcentrate ROM ore feed, SAG Mill scats and low grade or waste stockpiles Plant throughput increase, reduced operating costs and mine optimization should be considered in evaluating sorting as well as increased recovery in flotation and leach circuits The economic benefit to the operationThe processing of the ore should always be considered in relation to the mineralogy (Wills and NapierMunn 2006) 4211 Liberation Liberation of the valuable minerals from the gangue is achieved by comminution The process is suitable for a variety of ore minerals, such as monazite, xenotime, allanite, euxenite, fergusonite andMineral Processing and Extractive Metallurgy of the Rare
