For example, eight Jameson cells replaced thirty-two mechanical flotation cells in the Goonyella mine in Australia in 1995, significantly reducing the flotation circuit's size and improving the plant's yield by 3.5% (Carretta et al., 1997). They can also be used to recover fine coal particles from tailings successfully.
The first gold flotation testing should be confined to an all-flotation method so that the experimenter can become familiar with the ore. Careful observation, coupled with experience in testing, will enable the operator to interpret the various phenomena. It is desirable that he shall have had practical operating experience so that he may know the …
Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.

a mill discharge and flotation circuit, namely the MillStar Model Predictive Controller (MPC) and the FloatStar Level Stabiliser. Both these systems were commissioned at Mandalay Resources' Bjӧrkdal Gold Mine. Once the desired stability was achieved at this site, flotation optimisation was also implemented on the Rougher and Scavenger banks.
The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to …
The mine is expected to have a mill throughput of 7,000t / d during its mine life of more than 13 years. It is estimated to produce 172,000oz of gold in the first year and an average of 150,000oz a year during the first five years.

The company said that the flotation cells are used with frothing reagents to separate gold and sulphides from the host rock. Once it has been ground into a fine powder in the jaw crusher and ball mill, ore is soaked in a hydrophobic reagent and then moved into the flotation cells where a frothing reagent is added creating bubbles.

Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.
