production of gold, shortening the process and increasing production efficiency. Therefore, it is necessary to consider some new flotation processes to improve the purification process of low-grade gold ore. Froth flotation, which is a favorable option for an integral step in gold extraction, has been widely used since the 1930s.1,2 The ...

Lyster had no training as a metallurgist but was a keen observer. After spending his days watching the flotation cells, Lyster began to experiment. In 1912, Lyster found that by varying the air flow though the slurry, (finely crushed ore mixed with water), he could float lead sulphide in one cell and then float zinc sulphide in another.

Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate …

Gold losses during flotation often occur within the fines fraction, which has been an ongoing issue that has challenged the gold mining industry. Subsequently, operations will attempt to coarsen up the primary grind to reduce the fine gold (free gold or sulphide gold) generation, resulting from over grinding. Under-grinding can then to lead to gold losses in the coarse …

If you watch the FROTH as it comes over the edge of the float cell you will notice as each bubble flows over the edge, the bubbles behind it will move to the front of the cell. This is because as the bubble moves forward the bubble behind is attached to the front bubble by collector molecules that are attached to common particles of mineral.
