Flotation frother mixtures: Decoupling the sub-processes ...

Jan 01, 2016  The froth phase is metastable (Exerowa and Kruglyakov, 1997), but to ensure its role during the froth flotation process it must persist long enough to reach the concentrate launder. Particles of optimum size and hydrophobicity provide much of the stability in the froth phase ( Ata, 2012 , Horozov, 2008 , Hunter et al., 2008 ).

1 Froth Flotation – Fundamental Principles

The basis of froth flotation is the difference in wettabilities of different minerals. Particles range from those that are easily wettable by water (hydrophilic) to those that are water-repellent (hydrophobic). If a mixture of hydrophobic and hydrophilic particles are suspended in water, and air is bubbled through the suspension, then the ...

Froth Flotation - Metallurgist Mineral Processing Engineer

When too much froth is added to the pulp, the froth will collapse when using frothers that are immiscible. This has important implications in dealing with run-away problems in a flotation plant. Pine oil Pine oil and its relative reagent - eucalyptus oil (used in Australia), are mixtures of terpene alcohols such

Nov 01, 2016  1. Introduction. Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O’Meara, 1939).Sandvik (1979) reported that HF creates a large difference in the minerals’ zeta potentials as the zeta ...
