Abstract: The use of centrifugal gravity concentration in the closed-grinding circuit of a gold-containing massive sulphide ore was tested on classifier underflow and overflow. A continuous Knelson CVD6 was retrofitted to the hydrocyclone underflow for recovery of Au and Pb at a coarser feed size. The objective
Continuous gravity concentration in Gold grinding circuits. Falcon in the grinding circuit. By recovering 15% of the feed mass on a small Falcon C1000 (30t/h) and treating only 12% of the cyclone underflow, one can easily recover over 80% of the gold by using continuous Falcon gravity units in the grinding circuit.
The target grind size is 80% passing 90 µm. Cyclone overflow containing solids of the required size flows to linear trash screens prior to entering the leaching circuit. Coarser solids are returned to the mill for further grinding, with a bleed to a gravity circuit to …
in gravity concentration. Gold has a specifi c gravity of 15.0 - 19.3, and a typical ore usually has a speci fi c gravity of about 2.6 (e.g. quartz is 2.7, Pyrite 5.0, Magnetite 5.3 and Feldspar 2.6). Only free gold particles can be recovered by gravity concentration, particles should be liberated by crushing and grinding before gravity ...
Either stand alone or combinations of gravity concentration and flotation, can produce a gold bearing concentrate that can then be fed directly to a batch or continuous intensive cyanidation unit. Treatment of a gravity/flotation concentrate by intensive cyanidation may be processed by the InLine Leach Reactor (ILR) developed by Gekko Systems ...
The results of gravity tests have indicated that 81% of the gold from the ground ore (-74 μm) can be recovered into a concentrate (Con.1) with a grade of 262 g/t Au at a 7.2% yield. A clean concentrate containing 1760 g/t Au at 33.8% recovery was found to be produced by the further enrichment of Con.1 via hand panning.
The use of continuous centrifugal gravity concentration in . The use of centrifugal gravity concentration in the closed grinding circuit of a gold containing massive sulphide ore was tested on classifier underflow and overflow A continuous Knelson CVD6 was retrofitted to the hydrocyclone underflow for recovery of Au and Pb at a coarser feed size.
The above mass balance shows a schematic of the proposed installation of a continuous Falcon in the grinding circuit. By recovering 15% of the feed mass on a small Falcon C1000 (30t/h) and treating only 12% of the cyclone underflow, one can easily recover over 80% of the gold by using continuous Falcon gravity units in the grinding circuit.

This applies also to concentrating and classifying equipment. Ball-mill and tube-mill liners retain gold—as much as 1000 oz. if grinding is done in water and a tenth of this if done in solution. Some mills retain as much as $3M in gold until cleaned out. Cyanide solutions that contain gold are absorbed by wood, and the metal is there held.
