Gold-bearing veins can consist of calcite or mostly sulfides—which often weather into iron-stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators. Iron-stained ground areas and gossans are basically another sort of color change in the ground surface.

Gold ores are classified "free-milling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an …

Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to ...
