    Estimating Process Design Gold Extraction Leach Residence

    May 01, 2015 Abstract. Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores.
