This study presents the results of the experimental studies done by using a KC-MD7.5 Knelson centrifugal gravity concentrator to recover gravity recoverable gold from the grinding circuit of Bergama/Ovacik CIP plant. 2. Materials and methods Gumushane-Mastra ore is an epithermal type gold ore deposit having
cost for a gravity circuit is much lower than that for any other process. Minimizing the Size of the Gravity Concentration Circuit Many process engineers view gravity concentration in gold grinding circuits as a nuisance and a security risk. In part, this is probably due to the chequered history of enhanced gravity
