Electrochemical recovery of minor concentrations of gold

This paper provides a novel clean technology approach for gold recovery from cyanide-free solutions with only minor gold concentration. Recently, Halli et al. (2017) described a method of silver recovery from zinc-containing solutions by means of cyclic electrodeposition-redox replacement (EDRR).

Gold extraction

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.
