What does Froth flotation mean? - Definitions.net

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The ...

Mineral processing | Energy EXchange

Why be energy efficient? Valuable minerals are extracted from rock via the process of comminution (crushing and grinding). This process can be further refined using various means of separation, such as froth flotation, optical sensors and centrifugal devices.

The froth-free flotation vessel comes by way of Eriez Flotation Division, which patented it in 2002 and marketed it under the name HydroFloat. It is intended specifically for an innovative flowsheet that addresses one of the biggest problems mining operations face: With more tonnages to process, and more fine-grained ore, comminution is demanding ever more energy. If flotation circuits could ...

Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
