And gold were commissioned at Newcrest’s Cadia Valley operation in New South Wales Australia. The primary objective of the installation is to recover coarse value-bearing composites that are lost to conventional flotation tailings without the need for additional power input for particle size reduction to improve mineral liberation.

Effect of pressure on bubble size in dissolved air flotation

Dec 01 2002 The bubble size decreased as the pressure increased up to a pressure of 3.5 atmospheres. Above this critical pressure the bubble size did not decrease with further increases in pressure. According to these experimental results it is not only costly but also unnecessary to maintain a pressure above 3.5 atmospheres if the goal is only to ...

Flotation columns: Getting the most from fine ores - Outotec

Figure 2. Flotation process within a column. Typically columns are suitable for ores with a particle size bellow 150 m. Larger particles tend to be too heavy to be kept in suspension. This size limit may vary depending on the ore density. Lighter ores such as phosphate are amenable to column flotation at larger particle sizes. Figure 3.

1 Froth Flotation – Fundamental Principles

Figure 4. If the contact angle is very small then the bubble does not attach to the surface while a very large contact angle results in very strong bubble attachment. A contact angle near 90 is sufficient for effective froth flotation in most cases. Figure 4: Contact angle between and air bubble and a solid surface immersed in liquid.

Coarse PartiCle Flotation

Of Coarse Flotation The ability to float coarse particles minimizes grinding requirements as only a small fraction of the feed is ground to the traditional liberation size – reducing energy consumption or increasing mill capacity. With maximum production of coarse reject material the ability to manage tailings is vastly improved.
