Froth Flotation Process

Froth flotation chemicals play a major role in the mining and processing of mineral ores. With the increase in consumption of base metals (such as iron, steel, aluminum, etc.) and precious metals (such as silver, gold, and platinum), mining activities for the aforementioned metals have surged globally.

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.

Recovery of PGMs from an oxide ore by flotation and leaching

Horn et al. (2017) successfully employed CNNs for feature extraction from platinum froth images that can be used to predict platinum grades. Wang et al. (2018) proposed a two-step strategy based on CNNs for feature extraction and classification of froth images and finally determining working condition of a gold-antimony froth flotation plant.

Effect on froth phase The presence of stable froth phases is very problematic during froth flotation. Gangue minerals such as talc with non-polar or hydrophobic basal planes and polar edges influence froth properties. The polar edges that interact with the water phase and aggregates of these gangue particles increase the interlamellar viscosity.

Trithiocarbonates for PGM flotation

The milled ore is fed to the flotation circuit where it undergoes froth flotation and then dried. The dried ore is smelted at the electrical furnace, and the extracted metal is sent to air or oxygen blown converters for sulphur removal. The platinum metal is then sent for refining where impurities are removed and the final product is produced.
