Elution behaviour of metals from carbon
2009-10-15 ELUTION BEHAVIOUR OF METALS FROM CARBON 475 Introduction Gold can be extracted industrially from ores by a variety of processes, and one of the most successful methods is the carbon-in-pulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.

IXOS – IXOS Gold Extraction
For gold mines, IXOS® replaces the active carbon process for gold extraction: • Higher adsorption efficiency=less lost to tailing or more poured gold per cycle. • IXOS ® is a clean extraction process that yields purer end product. • High Gold capacity (about 25g/kg, 10x more than carbon) • High selectivity (>97%, vs. about 40% for carbon)

Strategies for the optimisation of gold processing plants
Effect of pH on Au Recovery in the Presence of 0.25% Stibnite (After Hedley Tabachnick 1968) Extrapolating the above trend back to the ordinate axis we note that 100% recovery is once again achieved at pH 8.9 but with the reservation that gold recovery will reduce somewhat, and cyanide consumption increase, as the free CN- ion is replaced by dissolved HCN at the lower pH.
