  • INTERPRETATION OF FLOTATION DATA FOR THE DESIGN

    For a testwork laboratory treating a wide variety of ores, the most useful laboratory flotation machine is probably one with cells of 500, 1000 and 2000g capacities, with a different diameter impeller for each cell, with stainless steel or rubber covered impellers, glass or plastic cell bodies, and requiring an outside source of low pressure air.
