The pre-concentration test work (cyclone separation) has been completed by Bureau Veritas (Perth Western Australia), and the concentrate has been shipped back to Gekko's laboratory for further gravity separation
The plants are also highly flexible and could be suitably modified by addition of scrubbing and gravity separation
equipment to convert into plants for glass sand preparation if suitable raw material is available.
Gillerman comments, "The entire Lemhi Pass district is enriched in mid-rare earth elements, and our team successfully used lab-scale standard crushing, gravity separation
, and stepwise magnetic separation to provide a monazite fraction for detailed scanning electron microscope and microprobe analysis.
The traditional means of removing glycerin is mainly by gravity separation
or centrifugation [3, 5].
Instead Stephen plans to concentrate on new-build projects on the farm, having invested last year in a gravity separation
The pre-feasibility investigation was conducted to characterise the Matilda ore with the aim of determining head grade, comminution response plus testing the response to gravity separation
and precious metal recovery by cyanide leaching.
Otjozond intends to produce the lumpy concentrate which involves a gravity separation
plant after crushing and screening to produce 500,000 tpa of product containing 36 to 40% manganese.
This could be used in physical processes such as crushing, grinding and flotation, magnetic and gravity separation
, as well as a diluting agent in lixiviant preparation (a liquid used to selectively extract metals from an ore or mineral).
7m * Further drilling is expected later in the field season at Rotgulden (Q3/4 2011) * Tailings dumps at Kliening mining centre require sampling, this material from historical gravity separation
provides attractive early cash flow target * Existing mapping and trenching at Buchbauer-Bischofeck (Kliening) has confirmed parallel groups of vein swarms, veins can be 25m apart, vein groups 100m apart, individual veins to 2.
Volta" or the "Company") (TSX: VTR) is pleased to announce that recent metallurgical tests undertaken by SGS South Africa (Pty) Limited ("SGS") indicate that between 40% and 55% of gold at the Kiaka Project should be recoverable by gravity separation
in less than 3% of the mass.
Wet gravity separation
and froth flotation of waste plastics are considered costly compared to dry separation.
This allows gravity separation
of the sleeve from the container and allows 100% of both the PET bottle resin and the sleeve to be reclaimed.
