Frothers are usually added to the pulp just before its entrance into the flotation machine. The quantity of frother varies with the nature of the ore and the purity of the water. In general from .05 to .20 lbs. per ton of ore are required. Some frothers are more effective if added in small amounts at various points in the flotation machine circuit.

This is because the froth is becoming purer as the unwanted mineral, the iron pyrite, is being cleaned off of the bubble. Not only is the colour of the bubble changing but the size is as well, the weight that the bubble has to support is lessening as the impurities and un-liberated (locked) valuables are depressed.

Marmatite (Zn 1−x Fe x S), which is an essential resource for zinc metal production now, is the result that some zinc sites in the sphalerite (ZnS) lattice are replaced by iron atoms, so both have similar flotation behaviors or characteristics [1], [23].In general, when sphalerite contains more than 6% iron, it is called marmatite [23].Currently, the separation of marmatite …

Pyrite, an iron disulfide, is often associated with valuable minerals, such as chalcopyrite, galena, sphalerite, gold, and cobalt. During the flotation separation of multiple sulfide minerals, the pyrite is often depressed as the gangue minerals (Mu et al., 2016).Whereas it is often floated as the froth products using xanthate as a collector during the gold and cobalt …

Froth flotation is an effective method for separating chalcopyrite from pyrite, using various flotation reagent depressants to amplify both minerals' surface differences in hydrophobicity [7], [8].Generally, lime is the depressant of pyrite in most of the concentrator plants [9], [10].There are two aspects to the depression mechanism of lime on pyrite.
