    The above pretreatment stages can be changed based on ore mineralogy For a complex Au–Ag ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at <38 µmDiagnostic leaching was carried out to assess the nature of refractoriness [29]Depending on the results of the diagnostic test results, extraction strategies for goldRECOVERY OF SILVER, GOLD, AND LEAD FROM A COMPLEX SULFIDE ORE USING FERRIC CHLORIDE, THIOUREA, AND BRINE LEACH SOLUTIONS By R G Sandberg 1 and J L Huiatt 2 ABSTRACT The Bureau of Mines investigated a hydrometallurgical procedure to re­ cover gold, silver, and byproduct lead from a complex leadzinc sulfide oreRecovery of Silver, Gold, and Lead From a Complex

  • Leaching and recovery of gold from ore in cyanidefree

    A gold ore sample originated from an epithermal deposit with a composition shown in Table 2 was used as a feed material in the leaching experiments Xray fluorescence and inductively coupled plasma optical emission spectrometry (ICPOES; Thermo Scientific iCAP 6000, USA) were used to determine the chemical composition of the sample after total dissolution, whereas gold and silver wereMineral Processing If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest The easiest method for achieving this is by gravity separation This relies on the differenceMineral Processing – McClelland Laboratories Inc Reno
