Collectors are used to impart hydrophobicity on particles thus increasing their chances of reporting to the froth phase. Also the extent to which naturally hydrophobic gangue particles such as talcaceous minerals report to the froth can be reduced by the use of depressants. Thus the use of collectors and depressants will directly influence the extent to which hydrophobic particles report to

The collectors greatly increase the contact angle so that bubbles will adhere to the surface. Selection of the correct collector is critical for an effective separation by froth flotation. Collectors can be generally classed depending on their ionic charge they can be nonionic anionic or cationic as shown in Figure 6.
