oxygen in mineral flotation

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilicThis is used in mineral processing, paper recycling and waste-water treatment industri Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century...

Effect of Oxygen and Micro

This study investigated the effect of oxygen and micro-cracking on the flotation of low grade nickel sulphide ore The ore treated contained serpentine minerals which have a history of being difficult to process efficiently The use of oxygen as a bubbling gas has been noted to be effective because it increases the pulp potential...

Pulp chemistry in sulphide mineral flotation

The use of an oxygen rich flotation gas was found to be a suitable method for changing the oxidizing conditions and improving flotation under controlled conditions The flotation results were correlated to the oxygen content and the redox potential, parameters which describe the pulp chemistry conditions , PULP CHEMISTRY IN SULPHIDE MINERAL ....

Copper extraction

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant Sulfide smelting...

Flotation of gold and gold

A great deal of work has been reported on specific ores, but such studies rarely distinguish between the flotation of native gold and other gold minerals Flotation of gold ores covers a broad field and it is a rather difficult subject to generalize on Most problems in gold ore flotation are not connected with floating metallic gold...
