Gold elution process

Gold elution process

A process is disclosed for the recovery of gold and/or silver values from activated carbon, wherein they are adsorbed as cyanide complexes. The process uses an eluant containing sugar. The process

    If your gold balance overall dictates that you do a 4 or 6 or 12 ton elution per day, then your elution should be done in the same day to maintain the inventory balance- in a Zadra system 18-20 hrs recycle is not uncommon even honouring all metallurgical parameters- it also depends on the cell activity, frame quantity, power draw, water quality etc. monitor the column outlet tenour to the electrowinning cell and

    Jun 20, 2019 It was not, however, until methods for chemically desorbing gold from loaded carbon were developed, that the process came into widespread use for gold recovery from ore. The Micron elution procedure takes advantage of the enhanced stripping rate achieved with alcohol, but confines the alcohol to the closed stripping unit

  • Elution behaviour of metals from carbon 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

    The gold-rich solution from the elution process, the electrolyte, is circulated through three parallel electrowinning cells over a period of 16–24 hours. Gold and other metals are precipitated on steel wool cathodes, which are submerged in the circulating electrolyte. At the anodes, oxygen is formed and degradation of cyanide occurs

    the mechanism of gold adsorption is important because the CIP/CIL processes work as a result of the gold adsorption mechanism, which is a chemical occurrence. Factors that affect the adsorption of gold are discussed. Finally, performance monitoring methods that help control the operation of the CIP/CIL process are discussed. 2
