Found this on hazen site,they have a falcon and nelson bowl that Steve said that they would need in Ghana GRAVITY SEPARATION
If a mineral exists in an ore as discrete particles separable from the worthless rock (gangue), it is possible to physically concentrate the valuable mineral and discard the gangue. One relatively simple method, called gravity separation, relies on the difference in density of the mineral and the gangue. This technology can be applied to primary recovery, preconcentration, and final upgrading, as well as recycling and soil washing. Hazen's gravity concentration facilities are among the finest in the world.
Our laboratories contain small jigs, shaking tables, a Knelson concentrator, a Mozley vanner, and heavy-media separation equipment. Preliminary closed-circuit tests can be made with as little as a few kilograms of feed material.
The pilot-scale facilities are equipped to handle a variety of test programs on a larger scale. Samples as large as several tons can be fed continuously, either wet or dry, to the different concentrating units. Variable-speed controls, automatic samplers, rate-monitored process water, and agitated interstage storage tanks complete the facilities.
LOCATED IN THE PILOT-SCALE FACILITIES ARE:
An array of spirals Wilfley, Deister, and Gemeni shaking tables Reichert tray systems for pilot-scale 2.0- and 3.5-meter Reichert cone concentrators Pilot- and small production-scale jigs Cone and cyclone heavy-media separation systems
FOR PLACER GOLD EVALUATIONS, THE GRAVITY FACILITIES OFFER:
A conventional washing sluice system (Gold Miser) Standard sluices Scrubber trommels Mineral jigs Spirals Shaking tables Gold Wheel Knelson and Falcon centrifugal separators
