    Fast and Effective Gold Leaching from a Desulfurized Gold

    The effects of various leaching conditions for gold extraction from sulfur containing gold ore using acidic sodium chlorate solution were investigated. The contents of gold and sulfur from the ore were 55.7 g/ton and 11.67 wt %, respectively. It was found that the presence of sulfur greatly inhibited gold extraction.

    Diagnostic Leaching for Refractory Gold Ores SRK

    A diagnostic leach test can be very useful to qualitatively assess how gold occurs within the ore and the extent to which it may be refractory. Several different permutations of diagnostic leach tests depend on specific objectives, but they generally involve the sequential leaching of a gold ore sample with
