The i150 Gravity Concentrator is the smallest of the World famous iCONs. This is a gravimetric concentrator that uses enhanced gravity (G's) to concentrate the 'free' heavy minerals. It is also known as a centrifugal concentrator because of the centrifugal action of the spinning bowl. The process uses only water and an electric motor to concentrate the precious heavy minerals from a slurry.

May 01, 2017· This paper demonstrates a simple, minimally-invasive method of estimating the gold recovery rate of gravitational separation equipment used by ASM at alluvial gold sites in the Guianas. 1 To accomplish this goal, a local ASM group, mining an alluvial gold deposit, agreed to allow the research team to collect eight samples of ore material ...
ABOVE: A 40 cubic yard / hour exploration program in Wells, British Colombia, January 1985. Paul was hired to design and build the placer mining equipment and to setup and run the exploration phase. The exploration plant shown here was a scrubber/classifier trommel with twin 20" Centrifuges for primary recovery, and then the primary concentrate was auger fed to a 16" Spiral Cleaner.
In Rio Suerte, we also care about making an exploration and evaluation of alluvial gold deposits prior to starting work squarely in the mining and gold panning Motagua River. Here are some methods of exploration of alluvial gold that can be used. EVALUATION OF ALUVIAL DEPOSITS One of the most difficult task associated with placer.
