Flotation of Gold and Gold-Bearing Ores - ScienceDirect

2016-1-1 · Most problems in gold ore flotation are not connected with floating metallic gold. The flotation recovery of free gold (throughout the text free gold is synonymous with liberated gold) is largely affected by physical constraints such as the shape and size of the gold particles and the stability of the froth.

The flotation of gold bearing ores — A review -

Compared to the flotation of a clean gold ore with a low clay content, obtained from the same flotation plant, the flotation of the high-clay-content gold ore produced much lower gold grade and gold recovery. The degree of entrainment (ENT) was calculated and it was found that a high mechanical entrainment of gangue minerals occurred in the ...

Flotation kinetics of a pyritic gold ore - ScienceDirect

2011-1-17 · Research Highlights 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 of gold and gold-bearing ores - ScienceDirect

Gold occurs in a number of minerals, and the most important of these is metallic gold and the gold metal alloys. Gold particles in an ore deposit vary in size from large nuggets to particles locked in the crystal lattice of sulfide minerals. These sulfide minerals are referred to as gold carrier minerals and contain trace to minor amounts of gold.

Notes on flotation of gold and copper ores, mount

The Mount Morgan ore is virtually a mixture of iron pyrites, copper pyrites, and gold in a quartzose gangue. There are two types of ore broken in the underground workings - smelting ore containing 40 %-50 % silica, and ore too siliceous for economical smelting. This latter type of ore was treated by flotation, an approximate analysis being ...
