what is froth in mining

Flotation Froth - an overview ScienceDirect Topics

For example, froth flotation is a technique commonly used in the mining industry. In this technique, particles of interest are physically separated from a liquid phase as a result of differences in the ability of air bubbles to selectively adhere to the surface of the particles, based upon their hydrophobicity. The hydrophobic particles with the air bubbles attached are carried to the surface ...

What is Froth Flotation?

17/12/2020  Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water. Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed. Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores. More recently, froth flotation is being used for treatment of ...

Froth Treatment Explained Oil Sands Magazine

In an oil sands mining facility, the froth produced in Extraction is only 50 to 60% bitumen with a relatively high concentration of fine solids (up to 15%) and can contain as much as 40% water. This bitumen froth is further processed in Froth Treatment where water and solids are removed using a solvent or light hydrocarbon. This hydrocarbon greatly reduces the viscosity of the bitumen and ...

Froth Factor for Pump Sizing - Mineral Processing

The ‘froth factor’ is a measure of the air contained in the froth. It is quantified by filling a measuring cylinder or bucket, of known volume, with froth and measuring the froth column. After air dissipation the remaining water and solids volume is measured. The ratio of the original volume of froth to the remaining combined volume of water and solids is the ‘froth factor’. Measured ...

Froth Flotation and Gold Extraction - Manhattan Gold

23/07/2014  In gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s hydrophobicity. First, refractory gold ore is ground as finely as possible – usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed ...

flotation process Infoplease

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface. The waste material (gangue) settles to the bottom. The ...
