Chlorine Extraction Of Gold
Extraction Of Gold. bromine acts more energetically than chlorine, and has also been employed in the extraction. the recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine. cyanideprocess the extraction of gold by the cyanidemethod is of great technical importance.

The leaching and adsorption behaviour of gold ores
enhanced extraction was due to a combination of equilibrium and pregrobbing effects. Diagnostic leaching was used to show that mineralogy was not an important factor in the enhanced gold extraction in the presence of activated carbon for the ores. Kinetic models were developed for the leaching of gold from the ore, adsorption onto
