Ultrasonic elution of gold from activated carbon ...

Mar 01, 2003  The feasibility of the use of ultrasound for the improvement of elution of gold cyanide from activated carbon was demonstrated. Elution of both the laboratory and plant loaded carbon with different eluants was enhanced considerably by sonication at 40 kHz, when compared with similar systems not sonicated.

Elution behaviour of metals from carbon

Many gold plants process ores containing traces of mercury, but the deportment of mercury through the entire plant under different operating conditions is poorly understood. It is known that generally mercury follows gold through the cyanide circuit (Zárate, 1985) and loads onto the activated carbon, but only partially elutes with the gold.

surface of the activated carbon into the interior. The macropores allow for the rapid movement of adsorbates (species that will be adsorbed by the carbon, e.g. gold) into the activated carbon granules. Mesopores (100 Å to 500 Å) these are the pores that branch off the macropores that serve to allow the adsorbates to leave the macropores

A pilot-plant investigation in a NIMCIX contactor has shown that activated carbon can extract more than 93% of the gold in return-dam solutions. The average gold concentration in the barren solution was less than 0.003 mg/L from a feed averaging 0.048 mg/L. The carbon was eluted by the Zadra procedure. The operating conditions of the elution-electrowinning circuit are reported, and the elution ...

Strategies for the optimisation of gold processing plants

For efficient stripping of gold, from activated carbon, reversing the above is logical. Thus successful elution should be favoured by high temperature, high free cyanide, high pH, low ionic strength and the absence of calcium. This is an excellent starting point to commence elution optimisation.
