Northgate Minerals Posts Fourth Quarter Net Earnings of $0.07380000 ounces of resource in the Harrier zone at Fosterville. Looking into 2009 the heated leach circuit at Fosterville is scheduled for commissioning in March which will significantly improve gold recovery in the mill. We will also continue to spend heavily on near mine exploration at both of our Australian mines with the goal of significantly

Flowsheet development for Agnico Eagle& 39;s refractory goldThe Fosterville Gold mine is lo ed approximately 20 km to the East of Bendigo in central Victoria. The gold at Fosterville occurs as solid solution within disseminated arsenopyrite and pyrite.
cgm gold ore plant mineral processingHeated leach temperature at forsterville goldmine Processing smelting and refining gold World Gold Council. For extracting gold from lowgrade ores heap leaching is practiced huge heaps are sprayed with a dilute solution of sodium cyanide and this percolates down through the piled ore dissolving the gold.
The Metallurgy of Cyanide Gold Leaching – An IntroductionLeach Kinetics: The pH and the temperature of the reaction can affect the kinetics of the gold dissolution reaction. However the pH and temperature will also affect the kinetics of other deleterious reactions like those outlined above and determining the correct conditions for the leach can substantially affect the overall performance.

Northgate Minerals Corporation: Exhibit 99.3- Prepared by TNTThe final piece of the puzzle however is a proprietary heated leach circuit which will be commissioned in April 2009. Once fully operational we expect gold recovery to reach 90% a dramatic improvement over the 65%–75% norm before we assumed control of the mine.
Heated Leach Process Temperature At Forsterville GoldmineFosterville gold mine heated leach process M. Binks*1 and P. Wemyss2 The Fosterville Gold mine is lo ed approximately 20 km to the East of Bendigo in central Victoria. The gold at Fosterville occurs as solid solution within di sseminated arsenopyrite and pyrite.
Leaching metallurgy - WikipediaLeaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while impurity remain insoluble.These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings.
COMPARISON OF CYANIDE AND THIOSULPHATE LEACHING FOR GOLDBefore leaching the gold ore must be crushed and grinded into small particles usually particle size varies between 30 and 180 μm. Free milling ores are ready for leaching after crushing and grinding whereas refractory ores need pretreatment. It is important to pretreat a refractory ore before leaching to achieve better gold extraction.
The geology structure and mineralisation of the FostervilleIn 2 libraries. The Fosterville goldfield is hosted in Lower Ordovician turbidite sediments and is lo ed in the eastern margin of the Bendigo-Ballarat Zone. The sediments are an undifferentiated sequence of sandstones siltstones and shales which have subsequently been folded. The fold style varies from close-tight with an interlimb angle of 30-40 493 . Faults are well developed throughout
Cold climqte IeochingThe leach pad is stacked late March to late November only and the leaching continues with a 90-day leach cycle on ore stacked in 15 m thick lifts. Nominal production is 30 Mtpa of heap leach ore. Pregnant solution temperatures range from 20 to 8oC. The average irrigation rate is 9.6 LNm2 with371672 m2 under leach. The ultimate heap height will
The process design of gold leaching and carbon-in-pulp circuitsLeaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide.
Fosterville Gold Mine Heated Leach Process Gold Gold MiningInitial leach temperatures of 40 degrees Celsius were adopted with the view to use waste heat from the bacterial oxidation circuit which operates at a similar temper ature. “Heated Leach” te sts conducted on CIL feed at 40 degrees Celsius immediately sh owed benefits with a step increase in CIL recoveries over both plant and previous te
