Gekko is also working to provide a ''nonstandard option'' for clients to measure gold on carbon, utilising XRF technology." said Professor Staunton. By advancing the accuracy, regularity and consistency of sampling, the selfcontained, groundlevel Carbon Scout unit has demonstrated measurements in carboninleach and carboninpulp ...
Carbon in Pulp of Gold Silver. Loaded carbon is educted to one of two pressure stripping vessels which are used alternately. Loaded carbon from the CIP circuit assays to kg per tonne (150 to 250 troy oz. per ton) combined gold and silver. Loaded carbon from the CIP circuit contains about equal amounts of gold and silver.

Electrowinning. Electrowinning is most often used to recover gold and silver from eluates produced by the elution of activated carbon. From: Gold Ore Processing (Second Edition), 2016 Related terms:
After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as CarboninPulp (CIP), CarboninLeach (CIL), or Carbon Column (CC). Once absorbed, the gold is stripped from the Carbon and the impregnated stripping solution fed into the electrowinning process where the gold is recovered by electrolysis.
The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton.
The different electrowinning cells presently developed for recovery of gold from CIP eluates are compared and contrasted. The efficiency of operation for each cell is,discussed in terms of the electrochemistry of (a) gold deposition, and (b) packed bed electrodes. The advantages and problems associated with each cell design are presented and recommendations are made as...

Dec 01, 1988· Precipitation is also compared with electrowinning and is shown to have certain advantages for specific eluates. INTRODUCTION In the carboninpulp process, cyanide solution at high pH and elevated tem perature is used to elute gold from carbon. The gold is recovered from this eluate by electroplating on to wire wool as described by Paul [ 1 ].

A process is disclosed for the direct and selective recovery of gold and/or silver from carbonate solutions, such as sodium carbonate which is used as an eluant for gold in a carboninpulp process (CIP). The process comprises reduction precipitation of gold and/or silver from a carbonate solution having a pH in the alkaline range by the addition of stabilized alkali metal borohydride, such as ...
The effectiveness of the solvents in promoting gold desorption from activated carbon is in the order acetonitrile > methyl ethyl ketone ⩾ acetone ⪢ dimethylformamide > ethanol. Aqueous acetonitrile and aqueous acetone strip gold in < 8 h using 2–3 bed volumes at temperatures between 25 and 70°C.

Eluates containing soluble gold and silver from either a ZADRA or an AARL type elution are suitable for recovery in the Kemix Electrowinning cell. Electrowinning is a process used to recover metals (eg. gold and silver) from concentrated solutions by applying a voltage across electrodes immersed in a concentrated solution.

No attempt was made to reduce the gold concentration of the raffinate to below g/l because the bulk of this solution is recycled to the leach (Figure 1). Implementation of this process at an operating gold mine allows the raffinate bleed to be recovered by adding this stream to the main cyanide leach carboninpulp adsorption circuit. The ...
The gold may then be recovered by electrowinning or work on a mixedmetal intensive cyanide leachate type solution (700 ppm Au, 400 ppm Ag, 200 ppm Cu, 150 ppm Ni, Fe, and Zn) has ...
