Gravity Concentration in Artisanal Gold Mining
Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore. This latter …

Sepro Concentrators
The UF or Ultra Fine Gravity Concentrator solves a very specific fine gold recovery problem, and does it very well. Some gold ores contain carbon which can interfere with the leaching process, so flotation is used to remove the carbon before leaching. However, during the flotation process, extremely fine gold particles will float with the carbon.
