Oct 19, 2007 · 1.. IntroductionThe significance and value of mineral liberation analysis to the subject of applied mineralogy and metallurgical processing has been well documented (Jones, 1987, Petruk, 2000, King, 1993).Mineral liberation data are fundamental parameters used for

Understanding Mineral Liberation during Crushing Using ...

Understanding how compressional breakage influences mineral liberation is an important first step to identify ores that have suitable characteristics for pre-concentration. There are multiple models that consider particle size reduction for coarse comminution, but few of them include mineral concentration or mineral liberation.
