Als operates several ultrafine grinding mills for use inconjunction with benchscale and pilot plant flotation test programs. regrind mills available include an isamill, metso vertimill, deswik mill and metprotech mill. whole ore or intermediate concentrates can be ground as fine as 56 m to liberate valuable minerals. pilot plant flotation.

Conventional laboratory flotation also recovered 86 pct of the copper from the minus 38 m flotation feed in a 27.8pctcopper concentrate. combining the results for the two products mathematically, 93 pct of the copper was recovered by the splitcircuit method in a 28.7pctcopper.

More precisely, chalcopyrite is finely disseminated in the sphalerite, making a challenge to separate copper and zinc. to achieve this, it is necessary to consider ultrafine grinding to reduce the particle size down to 10 microns. nevertheless, grinding very finely presents problems of its own and thickening also becomes problematic.
