Cut-off grades for mineral resource reporting: going the extra rare earth mile Resource Geologists are geologists who can value the basic underlying economic attractiveness of a mineral deposit This means knowing the costs and practicalities of mining and processing for a particular product

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry The particles ,

Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size
