Abstract
The authors have tested effect of type and energy of mechanical impact on selectivity of spodumene ore breakage in a disintegrator and in vibratory and ball mills in terms of pegmatite with lithium content of 0.1%. It is shown that the highest efficiency of mineral dissociation is achieved in disintegration by free impact. Analysis of grain-size distribution and chemical composition and the X-ray study also reveal advantage of the disintegration process, which allows higher content and recovery of lithium in concentrate at reduced sliming.
