How much Frother is Required: Dosage

The quantity of frother required in sulfide ore flotation is generally less than 0.15 pound per ton of ore, with some plants operating on as little as 0.015 pound per ton. Control of the quantity of frother is generally not as critical as is collector control. However, choosing the proper frother is extremely important. Froth quality often depends on other factors than the frother itself, and no single frother can function best for all applications. Usually the proper frother can be determined only by the results of laboratory experimentation, complemented by actual mill testing. Similarly, choosing the proper collector-frother combination is extremely important.
