Flotation Cells
More ores are treated using froth flotation cells than by any other single machines or process. Non-metallics as well as metallics now being commercially recovered include gold, silver, copper, lead, zinc, iron, manganese, nickel, cobalt, molybdenum, graphite, phosphate, fluorspar, barite, feldspar and coal. Recent flotation research …
Synergistic effects of Reflux Flotation Cell's
Apart from the entrainment of normal fine particles during flotation, clay minerals with a particle size normally smaller than 5 μm also undergo aggregation, generating aggregate structures which compound the entrainment problem. The aggregation behavior of clay minerals is attributed to their complex crystal structure, …
