01 Gold ore flotation process and equipment. Gold ore flotation process is a common method for extracting gold. It is based on the principle of selectively attaching air bubbles to hydrophobic particles (gold) and separating them from hydrophilic particles (surrounding rock minerals). The process includes the following steps:

Coarse gangue rejection essentially uses flotation cells as an ore sorting technology. "It's an ore sorting technology, except it sorts material at maybe half a millimeter, as opposed to conventional sensor-based ore sorting, which decides whether a 6-in. rock can be differentiated and disposed of before it goes through the plant ...

The flotation rate constant is also affected by particle size. Many iron ore concentrators use the quantity of +100 mesh (.15mm) material in the flotation feed as a measure of the performance of the grinding circuit. 100 mesh particles are well within normal flotation range and present no particular problems.
