  • Ore processing – Waihi Gold

    Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. ... This ‘loaded’ carbon is then pumped to the elution circuit (6) where the gold and silver is washed off with ...

  • Carbon in pulp Wikipedia

    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. ... The final loaded carbon then is removed and washed before undergoing "elution" or desorption of gold cyanide at high temperature and pH.

  • Elution and Carbon Reactivation Resource book

    During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

  • Elution behaviour of metals from carbon SAIMM

    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 carboninpulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.
