After cyanidation the gold may be recovered from the solution by adsorption on activated carbon (McDougall and Hancock, 1981, Tsuchida et al., 1984, Bailey, 1987). The main carbon adsorption technologies are carbon-in-leach (CIL), carbon-in-pulp (CIP) and carbon-in-column (CIC) processes. After gold adsorption, the loaded carbon is separated by ...
The vibratory gold wash plant, the SV6, is rated up to 180 tons per hour. This design allows for nuggets and fine gold recovery. Its horizontal design allows for much lower feed height and improved cleaning action of materials. It accepts up to 8-inch material and incorporates two decks for thinning and separation.

Traditional methods for the recovery of gold from electronic scrap by hydrometallurgy were cyanidation followed by adsorption on activated carbon or cementation onto zinc dust and by electrowinning. In our studies, a static batch electrochemical reactor operating in an electrogenerative mode was used in gold recovery from cyanide solutions.

Cyanide Leaching Of Gold. Gold Cyanide Solution Leaching Gold With Cyanide Since the 1890s cyanide has been used to recover gold from gold bearing ores And today over 115 years later most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.

DOI: 10.1016/j.chemosphere.2008.07.014 Corpus ID: 41390411; Electrogenerative gold recovery from cyanide solutions using a flow-through cell with activated reticulated vitreous carbon.
The performance of the reactor was evaluated with initial gold concentrations of 10, 100 and 500 mg L-1 and various electrolyte flow rates. Gold recovery was found to be strongly dependent on electrolyte flow rate and initial gold concentration in the cyanide solution under the experimental conditions used.
If the solution is rich enough can be treated by zinc powder and the precipitated obtained (cement) obtained will be sent to retorting and smelting. For gold extraction the strength of cyanide solution ranges from 0.01 to 0.05%. Lime is added to the process in order to have a pH near to 10-11.
Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

The effect of the cyanide complex impurities on carbon adsorption of gold was determined by adding sodium gold cyanide to the synthetic feed solution, producing a gold concentration of 150 ppm. This concentration is signif. icantly higher than metal concentrations normally encoun tered in most gold plant solutions; however, the results are
