The results were fully up to expectations from the very start. This plant consists of 8 rougher and 2 cleaner cells and treated 500 tons per 24 hours.

Geco Flotation Cells. In the Geco New-Cell Flotation Cell the pneumatic principle is utilized in conjunction with an agitating device. The machine, which is illustrated in Fig. 44, consists of a trough or cell made of steel or wood, whichever is more convenient, through the bottom of which projects a series of air pipes fitted with circular ...

Gold particles in an ore deposit will 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 (Taggart, 1927, Chryssoulis and Cabri, 1990).Often it is found that gold ores are refractory due to the small size of the gold …

in the laboratory tests and phase 1 pilot tests, the main aim was to determine if the flotation in the Hydrofloat® cell could recover more than 95% of the gold content from the gravimetric tailings. Having confirmed the feasibility of achieving this level of recovery, Mineros s.a. decided to assess the high grade gravimetric tailings and

For the flotation tests, a gold ore slurry was prepared with 35 wt.% solid pulp density. The prepared pulps were mixed with 70 g/t of KAX, 35 g/t of AP3477, and 40 g/t of PPG for 10 min at 1200 rpm. The tests were performed in the first cell of the rougher 1 bank (#1 Rougher 1). The flotation cell was a Denver sub-A type (, Finland).

Tests made on ore containing $9 gold, 3.5% copper, and 45% insoluble, showed that after crushing to pass 60 mesh and treating by direct flotation, an extraction of 82% of the gold and 96% of the copper could be obtained, with a concentrate containing only 21% insoluble.

The variations are not large, either with cell size or cell design. Older pneumatic cells, which used compressed air along without injection or impellers, had higher escape velocities, averaging 2.9 m/min (9-10 ft/min) for the Callow and Forrester designs.
