GIW High Volume Froth (HVF) Pump The HVF pump is designed to work with slurry processes that use froth to help separate materials during processing. GIW's pump can be used in a wide variety of mining and processing industries, from oil sands to phosphate plants.
The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled . After this stage the enriched ore now contains about 25% copper by mass.

Demonstrates strong froth generation and froth persistence, producing welldefined bubbles and uniform froth generation downthebank. POLYFROTH ® H57 Hydrophobic and produces a strong, drier froth characterized by a fine structure and mobility.
The froth of copperrich bubbles at the top of the tank is then skimmed off for further processing. The gangue sinks to the bottom of the tank to be removed or disposed of as mine tailings . The next stage after froth flotation is the thickening stage.
Different processing methods are used by mining companies to separate out valuable minerals from other unwanted waste minerals. This experiment demonstrates how froth flotation uses special chemicals and air bubbles to float unwanted minerals away.
The froth is then dried to recover the mineral particles. The importance of froth flotation process is that, it is easy to separate two sulphide ores present in a mixture (by adjusting the oilwater proportion or by using depressants).
Australias minerals industry is a world leader in innovation and developing and adopting transformative technology from commercialising froth flotation for minerals recovery in the 1860s in Broken Hill to introducing remote control iron ore trucks in Pilbara in the 2000s.

The sensor can measure the stiffness of the froth, the thickness of the froth, analyse the interface area between the froth and the slurry and it can analyse the slurry too depending on the customer needs," says Jukka Hakola, Numcore's Vice President of Sales and Marketing.
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 disadvantages of above froth addition is the froth disturbance and wash water shortcircuiting to the concentrate. The higher the distance between the distributor and the froth surface, the higher the impact velocity of water droplets on bubbles.
Froth flotation is a common process for the separation of liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals.
