At the Fort Knox Mine Fairbanks Alaska carbon fines are generated during stripping acid washing and kiln regeneration operations. Because of their gold value carbon fizzes are collected by a.
The high temperature and high-pressure desorption method is to install the gold-loaded carbon in a pressure vessel and mix the solution with 0.4 to 1 NaOH and 0.1 NaCN heat temperature to 130 to 160 C under the pressure of 3.6 to 5.9 kgcm2. Within 2 to 6 hours the gold and silver desorption rates of gold-loaded carbon exceeded 90.
Desorption electrolytic equipmentour desorption electrolysis unit is a new style high efficiency product integrated with new technique and technology.it is used to treat gold carrier carbon in gold production.this unit can perform outstanding desorption function for gold carrier carbon from carbon-in-leach plant and heap leaching plant.mob 0086-199 7091 7965.
May 24 2018 The main difference between CIL and CIP lies in the extent to which gold is leached prior to carbon adsorption. In CIL operations carbon is added to the leaching tanks therefore the leaching reaction and adsorption occur simultaneously. During the CIP process most of the leachable gold has been leached prior to the first adsorption stage.
The pregnant liquor discharged from the cyanide tank is pumped to the adsorption tower where the activated carbon adsorbs the gold and the barren liquor flows to the barren liquor tank. E. Desorption electrolysis and smelting. Gold-loaded carbon goes through the desorption and electrolysis process or burning process to get the gold mud.
The carbon size is 0.6-0.8mm. The actual gold adsorption rate could reach 95-99. 5 Desorption and electrowinning. The loaded carbon is treated by desorption and electro-winning equipment after it could get high grade gold mud. 6 Gold melting system. The gold mud feed into the smelting equipment to get the final pure gold bars 99.
Carbon Adsorption In Recovery Of Gold. From Cyanide Leach Solutions. It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years and many papers have been written on the subject. Carbon as a media of recovery for gold from leach solutions did not gain wide acceptance in the gold industry until.
The best known application for activated carbons in the mining sector is for the extraction and recovery of gold Au although it is also used for some other precious metals. In the gold recovery industry there are three main methods for extraction of the metal all of which use granular activated carbon in the recovery of gold from cyanide.
