CA2898420A1 Method for leaching gold from gold ore

Provided is a method for leaching gold from gold ore containing pyrite. Said method for leaching gold includes a pretreatment step that includes a step (1) in which gold ore containing pyrite is prepared, and a step (2) in which the gold ore is heated to 450°C or higher, and the pyrite in the gold ore is thermally decomposed into iron(II) sulfide and elemental sulfur.

Improving the gold leaching process of refractory ores

Apr 01, 2019· The same amount of gold ores which is leached for over 24 h to obtained +80% Au recovery; can be leached for less than 3 h (using the Jetleach reactor) to get the required Au recovery (+80%). Due to it fast kinetics, leaching, using the Jetleach, will result in an increase in gold production per unit of ore processing.

Recovery of gold from hydrometallurgical leaching solution

Aug 01, 2017· The rate of gold recovery and the concentration of gold ions remaining in each solution were determined from the UV–visible absorption peak at about 312 nm. The reduction of AuCl 4 ion to elemental gold and its deposition on the surface of polyaniline films or PANi coated cotton fibers were readily confirmed by the XPS measurements.
