elution in gold mining

Fouling of carbon, regeneration and Elution . 02/04/2016· Elution of gold from carbon Over the last 10 years there has been much research and development into elution procedures, all trying to improve on the traditional Zadra Process [37] which takes days to complete Recent studies by Adams and Nicol on the kinetics of elution [38] show that NaCN is more effective than NaOH as an eluant and ...

Elution behaviour of metals from carbon

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.

1.4 Zadra process description Tau Lekoa stream uses the Zadra process. The eluant is continuously circulated through the column and an electrowinning cell in series. A caustic cyanide solution, normally 0.2 to 0.5 % NaCN and 2% NaOH, is pumped to the elution column and is pre-heated by the solution leaving the column.

Not process water. E/W single pass efficiency is critical for Zadra because gold not recovered is then re-circulated back to the elution column, slowing down the elution rate. Eluant flowrate is not too critical in the 2-4 BV/h range. You should be achieving optimum elution with about 30 BV of eluant through the column (15h at 2BV/h).

There is some analogy between the results of this study and that of Adams and Nicol [ 5 ], who found that solutions containing greater than l 0 g/l NaOH solution gave poorer results than the l 0 g/l solution.
