Air Rougher Platinum Flotation Process

Most mines process the UG2 ore from open pits and routinely suffers from low and erratic platinum group element PGE flotation recoveries. This is due to changes in mineralogy of the ore as a results of oxidation. In the past, these ores were left in situ, stockpiled or discarded owing to their poor flotation

An Overview Of Optimizing Strategies For Flotation Banks

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies air profiling, mass-pull froth velocity profiling and Peak Air Recovery PAR profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited.

A Practical Approach To Plantscale Flotation Optimization

A technique has been developed using the Anglo Platinum Bubble Sizer on an industrial flotation cell to determine the relationship between bubble size and frother concentration. This technique has been extended to measure the equivalent frother concentration or frothabilities of various streams on a rougher bank. A mass balance

Pneuflot Pneumatic Flotation Technology An Alternative To

Conventional agitator-flotation systems are less sensitive to feed variations, but changing conditions, especially where base metal minerals are being processed, decreases the ability to control the process. Likewise, with column flotation technology, the particleair collision time in a single cell is very low, making selectivity very high.
