CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION

2020-5-6 · Frothers, as defined by flotation operators, are compounds used specifically for creating a flotation froth. However, most collectors used in iron ore processing produce adequate froths. The general types of these frothing collectors include long-chain carboxylates, sulfonates or sulfates, and amines as listed in Table 9.1.
