Enhanced dissolution of minerals: Conjoint effects of particle size …
Experimental determination of representative α-values obtained from scanning electron micrographs of three crushed minerals (sphalerite, ilmenite and chalcopyrite) suggest that the limiting milled particle size for significant microtopography-enhanced dissolution lies within the range from ∼ 0.2 to ∼0.4 μm.
