Application of gamma emission imaging in mineral ...

Apr 01, 2011  The gamma emission imaging technique has been effectively applied for determination of the slurry radial flow pattern and mixing profile within the ball charge in a wet laboratory ball mill. Aqueous technetium, Tc 99m radioisotope that emits 140 keV photons with a short half-life of 6.02 h, was utilized as a flow follower while the glycerol-water mixture was used to mimic the motion of the ...
