  • The process design of gold leaching and carboninpulp

    The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concentrating factor of about 1 000–1 500 A portion of the loaded carbon is periodically removed from the first gold extraction after leaching by cyanide in aerated alkaline slurries The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carboninpulp (CIP) and the carboninleach (CIL) processes, have been widely used since the 1970s Due to the economic importance of these processes, their simulation hasDYNAMIC SIMULATION OF THE CARBONIN PULP AND CarboninPulp (CIP) and CarboninLeach (CIL) processes have surface areas of about 1000 m²/g ie one gram of activated carbon (the amount of which will occupy the same space as the end of a person's thumb) has the same surface area as two football fields The high surface area is contained in the millions of pores of varying sizes, these beingACTIVATED CARBON IN GOLD RECOVERY Kemix
