1 Froth Flotation – Fundamental Principles

2009-8-27  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 hydrophobic particles will tend to attach to the air bubbles

Froth Flotation - Metallurgist Mineral Processing Engineer

2016-12-19  When mineral-bubble agglomerates reach the surface of a flotation cell, the bubbles can break and thecollected mineral fall back into the slurry. To prevent this loss, a frother is added to produce a frothphase stable enough to hold the floated particles until they can be removed from the cell.

2009-7-30  froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.

IX. FROTH FLOTATION

2012-8-10  IX. FROTH FLOTATION Froth flotation is a process used to separate minerals, suspended in liquids, by selectively attaching them to gas bubbles. Hence, in flotation we have a three-phase system. The separation principle is based on the lack of affinity of the mineral surface towards water, a property denoted by hydrophobicity.

Froth flotation characteristics study was carried out on Yeongwol Sangdong mine Scheelite ore in order to produce WO3 concentrate using oleic acid as collector. In case of using oleic acid, due to the low selectivity of the purpose mineral, the selection of the gangue mineral depressant and pH adjustment are important. As a result, it was confirmed that the optimum pH for providing optimum ...
