The future of flotation

Nov 04, 2016· Low grades, complex ores and rising energy costs have prompted the development of entirely new flotation vessels, improvements to existing technology, and new thinking about flotation flowsheets. The froth-free flotation vessel comes by way of Eriez Flotation Division, which patented it in 2002 and marketed it under the name HydroFloat.

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

95-99% by grinding to fairly fine particle size, gravity separation, cyanidation and flotation, all of which increase capital and operating costs. In some cases, oxidation of sulphide minerals is needed to liberate gold that is occluded within the sulphide matrix. Sulphides can be oxidized by several methods, and the overall costs are similar.

Mine operating costs and the potential impacts of energy

Feb 01, 2014· Thus if it is possible to grind the ore to a coarse size, in the range for example of 400–1000 μm, separate the particles containing valuable minerals, and then regrind only these particles to a final size suitable for conventional flotation machines, there would be very significant cost savings.

Minerals

In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals. In order to achieve this, comminution circuits usually consist of
