Hidden Valley Mine Mining Intelligence and News

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.

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 [29].Depending on the results of the diagnostic test results, extraction strategies for gold
