Cyanide Leaching Of Gold, Laboratory Bottle Tests

Gold Cyanide Solution, Laboratory Bottle Test Method This is one method for doing cyanide bottle leaching tests for determining the 'leachability' of gold and silver by leaching with cyanide. Take the ore to be leached and crush it to a size that will fit into a pulverizer (usually 1/4"). Then feed the ore to a pulverizer and grind to 100 mesh.

carbon as a sodium or calcium/gold cyanide ion pair (2) is desorbed from the carbon by a reversal of the adsorption kinetics. Gold is recovered from the pregnant strip solution by electrowinning onto steel wool. The gold depleted solution is then reheated and recycled to the carbon bed for reuse (see Figure 1).
