Recovery of gold from secondary sources—A review ...

01.03.2012  The gold recovery was found to occur via the reduction of trivalent gold ions present in the solution to metallic gold, which was proven by SEM images and XRD patterns. It was shown that increasing the shaking rate and contact time leads to an increase in the gold recovery efficiency. Among all parameters investigated in this study, the shaking rate and temperature play a vital role in the ...

Gold extraction - Wikipedia

These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach solution to form a complex with the gold. Organic carbon present in gold ore may adsorb dissolved gold-cyanide
