The Hidden Valley process plant was designed to treat nominally 4.1Mtpa of gold/silver bearing ore. The process uses a two stage crushing circuit followed by a SAG mill, gravity, CCD/Merrill Crowe circuit for silver and a carboninleach circuit for the gold. A silver/gold ore bar is produced and flown off site for refining and sale.
productivity. By running thorough agitation studies on your ore samples, we make sure we recommend the right equipment for your process including for refractory ore processes like pressure oxidation and biological leaching. Gold Recovery GOLD Carboninpulp (CIP) is the sequential leach and adsorption of gold from ore. During the leach, pulp
1.1.5 Ore extraction After a mining company has removed overburden, extraction of the mineral ore begins using specialized heavy equipment and machinery, such as loaders, haulers, and dump trucks, which transport the ore to processing facilities using haul roads. This activity creates a unique set of environmental impacts, such as emissions of

Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard benchscale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanideconsuming ores.
The above pretreatment stages can be changed based on ore mineralogy. For a complex AuAg ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at <38 µm.Diagnostic leaching was carried out to assess the nature of refractoriness .Depending on the results of the diagnostic test results, extraction strategies for gold
mining mining Underground mining When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the

Gold extraction from ores that contain >0.5% Cu is often uneconomic by traditional cyanide leaching. High cyanide concentrations (CNCu>4) should be maintained to achieve high gold extractions.
West Province. The mine produces around 450 kg of gold a month. The ores from the mine are treated in a separate stream at Kopanang Gold Plant. The Kopanang Gold Plant is a modern plant that uses millleachCIP electrowinning processes. The gold from the electrowinning process is smelted centrally in another plant situated 5 km away from Kopanang.
