The impact of water quality on flotation performance

The impact of water quality on flotation performance

The impact of water quality on flotation performance pH, Eh, DO and dissolved species in recycle water streams (e.g. thickener overflow, decant (tailings) dam return) contributing to a circuit water are also shown in Table I. TDS and TOC levels may also be raised by reagent addition for pH control (e.g. lime) and recycled organics (e.g. depressants,

Flotation Process In Mining

Flotation Process In Mining

Flotation is a mineral separation process done in the water medium. It is based on the difference in the surface properties of the mineral and gangue. The surface of the selected mineral is made hydrophobic (water repellent) by the use of selective reagents and these particles get attached to the air bubbles that are introduced in the system and collected as froth whereas the hydrophilic ...

Parametric Optimization in Rougher Flotation Performance

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1000 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery.
