Hendriks G. Chevalier Hemlo Gold Mines Inc. The Golden Giant Mine P.O. Box 40 Marathon, Ontario POT 2C0 ABSTRACT The installation of gravity concentration circuit at the Golden Giant Mine has resulted in some surprising results.Gravity Gold-Selection Sizing & The Optimum,Gravity gold recovery was mandatory for the oxide ore with 42.9% of the gold recoverable into a gravity concentrate of 0.76 mass percent using a Knelson concentrator. The microscopic examination of the gravity concentrate revealed abundant free gold up to 500um in size and down to 0.5um.
Gold was subjected to the gravity concentration device in its coarsest state, i.e., as soon as a particle was discharged from the mill it saw the gravity concentration device. There were also some disadvantages: The gravity circuit had to process 3 or 4 times the new feed rate to the mill (the entire circulating load).Improvements in Gravity and Overall Gold Recovery at,Improvements in Gravity and Overall Gold Recovery at NVI Mining Ltd.

When separating free gold from a typical quartz deposit, gravity concentration must separate based on specific gravities of 19.3 and 2.6, for gold and quartz respectively. The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer.Recent Improvements to the Gravity Gold Circuit at,The gold recovery from the gravity circuit averaged 17% over the 18 month period (Oct-08 to Mar-10) prior to the gravity circuit upgrade.Gold Extraction - Citigold,The CIL plant is fully equipped with crushing and grinding circuits, small gravity circuit for coarse gold, gold absorption and desorption leach circuits, electrowinning and gold pouring facilities. The plant has operated efficiently, recovering around 97%
Figure 1 – Gravity Recovery as a Function of Knelson Weight Recovery Once it was determined that there was a relationship between Knelson concentrate weight (as determined by Knelson cycle time) it was decided to investigate this further. In January 2005, Knelson Gravity Solutions was contracted to carry out an audit of the gravity circuit.Optimising circuit design for gravity gold,To determine the optimal circuit configuration for gravity gold recovery consideration should be given to a range of factors in addition to the efficiency,gravity gold recovery circuit ,The Gulin product line, consisting of more than 30 machines, sets the standard for our industry.
