Nov 14 2022The process is commonly used for sulphide ores This is because pine oil used in the process selectively wets the sulphide ore and hence brings it to the froth Froth flotation can primarily be done under two common techniques Direct floatation technique The mineral sticks to the air bubble and the remaining gangue settles down at the bottom

Radio Hill in Australia successfully used the Ausmelt reagent AM28 an alkyl hydroxamate to float mixed sulphide/oxide copper ore increasing recovery from a low of 40 to 50% up to 70% They used AM28 to replace sulphidisation of oxide minerals in conjunction with standard sulphide collectors to recover sulphide minerals

Mixed collector systems for the improved flotation of these sulphides are proposed as a solution The use of xanthate and dithiophosphate in the collector suite allows the co existence of dixanthogen and free dithiophosphate radical because the latter has a higher redox potential requirement than xanthate to oxidise to the dithiolate
