THE EFFECT OF ACTIVATED CARBON PARTICLE SIZE ON …
temperature, pressure and composition of the strip solution used in the elution process are factors that are interdependent in the influence they have on the elution of gold cyanide from activated carbons. These factors must all be set at their proper levels in order to maximize the rate and amount of gold desorbed from the loaded carbons.

Gold Ore Mining. Placer gold mining mainly refers to mining from the land surface or river or underground. It mainly uses gravity separation because its density is much bigger than other minerals. Compared with placer gold, rock gold ore has higher gold content and mining value, but the beneficiation process of rock gold ore is much more complicated than that of placer …

1.1 Elution. CN- or OH- dissolved in desorption solution is easier than Au(CN)2- to be absorbed by the activated carbon which causes Au(CN)2- absorbed on loaded carbon is replace by CN- or OH- and the reversible balance of of gold adsorption is broken. This processing is named as gold desorption (elution, stripping). The reaction formula is below:
