constants and recovery to increase as the cell size increased from both the 2 and 4 l cells to the 7.5 l cell. However, when increasing the cell size from 2 l to 4 l, good results were also observed for all impeller speeds. The products concentrate seem to become finer when decreasing the cell size, with only a few exceptions.

Flotation & Shaking Tables with Open Circuit Ball Mill

DESCRIPTION: Flotation followed by shaker table concentration in open circuit grinding. ORE TREATED: When the mineral in an ore is freed at a coarse mesh, this flowsheet gives high recovery and high capacity. The practice is limited in scope, as on ores requiring fine grinding, closed circuit is preferable, and on ores wherein the gold is free, amalgamation or cyanidation alone or with ...
