Correlation of air recovery with froth stability and separation
1. Introduction. Froth flotation is one of the most important and widely used methods to separate one type of particles from another. Froth monitoring and control is increasingly being adopted in hard rock mineral flotation plants for improving separation efficiency since froth structure and stability plays an important role in determining flotation product grade, throughput …

Spodumene is commonly concentrated by heavy media separation, froth flotation and/or magnetic separation. Prior to leaching, natural spodumene (α-spodumene) is converted to irreversible β-spodumene by heating at about 1000–1100 °C because the β-spodumene phase is much more reactive and less resistant to ordinary chemical agents.

Froth flotation is the most effective method to separate and enrich refractory calcium-containing minerals. Because the calcium ions in the mineral lattice are the same, they have similar surface chemical properties and dissolution characteristics (solution chemical properties) in the slurry environment [29], [30], [31], resulting in a lack of selectivity in the adsorption of flotation ...

Froth flotation works by rendering the surface of valuable minerals hydrophobic so they can attach to air bubbles. The bubbles carry the hydrophobic minerals to the surface, where they can be removed from waste rock.
