Has any one tried extracting plated gold by disolving the gold plated items in cyanide and then seperating the gold from the cyanide? The only way to gold plate copper or brass is to first plate the surface with nickel. For allumnum they first plate with copper then nickel and then a final layer of gold. It seems to me cyanide would instantly disolve …

Interpretation. The chart above displays the 1-year rolling correlation coefficient between the price of Copper and the price of Gold for a 1-year time window, commonly referred to as the rolling correlation. A correlation coefficient of +1 indicates a perfect positive correlation, meaning that the two metals moved in the same direction during the specified time window.

Iron oxide‑copper‑gold (IOCG) deposits are a rare type of magmatic-hydrothermal deposits that were initially proposed for the giant Olympic Dam deposit and Cu-Au deposits in the Cloncurry region, Australia (e.g., Hitzman, 2000; Williams et al., 2005; Groves et al., 2010). They are commonly hosted within breccia bodies and are related to ...
