Predicting Flotation Recovery Metallurgist Mineral Processing Engineer
Predicting Flotation Recovery. Unfortunately many milling engineers rely rather heavily on percent recovery as a strict measure of a concentrator s relative performance. The fallacy of this reasoning is not difficult to see since by definition percent recovery is a function of feed assay tails and concentrate grade.
Major Mines Projects Grasberg Mine
Mine Life. 2019. PTFI began openpit mining of the Grasberg ore body in 1990. The final phase of the Grasberg open pit was mined during 2019 including the removal of the open pit ramps. In aggregate the Grasberg open pit produced over 27 billion pounds of copper and 46 million ounces of gold in the 30year period from 1990 through 2019.

Effect of strong collectors and frothers on coarse particle flotation
Sep 22 2022ABSTRACT. In conventional flotation particles larger than 150 μm tend to float poorly especially those with high specific gravity.

The Implementation of FloatStar GradeRecovery Optimisation Control
The mineral grades in concentrate streams are a critical performance indicator in any industrial flotation circuit. Failure to achieve concentrate mineral grade targets has significant financial consequences on a flotation operation. A violation of a gangue mineral grade limits by the concentrator may also result in significant penalties.
Flotation Mineral Processing Metallurgy
The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations

Jameson cell Wikipedia
The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1) and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for
