A number of bed volumes of hot water are then pumped through the bed of carbon to eluate the gold. The gold-containing eluate is collected in the electrolyte tank. 4. Carbon regeneration

The Metallurgy of Cyanide Gold Leaching An

2014-10-20  Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing

The leaching and adsorption behaviour of gold ores

2020-8-28  adsorption onto activated carbon, these effects include competing metal-cyanide complexes, preg-robbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling viewpoint. In this research it is shown that a variety of metal-cyanide species can be used to leach gold from certain refractory ores.

Recovery of gold by a carbon-in-pulp process

A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.

Arsenic Pyrite Gold Extraction by Alkaline Leaching

2017-7-22  Gold recovery was proportional to arsenic extraction during the oxidative leach, with >90 pct Au extraction for arsenic extraction ≥ 89 pct. Silver extraction did not follow this trend and ranged from 47 to 62 pct. Cyanide consumption was 2.6 kg NaCN per metric ton of leach residue and 5.7 kg NaCN per metric ton for the untreated ore.

Strategies for the optimisation of gold processing plants

Cyanide. Oxygen is oxidising the gold not cyanide and substandard performance of leach circuits will 9 out of 10 times be due to low dissolved oxygen levels rather than low cyanide levels. Referring back to the AMIRA conclusions we note that loading of gold onto carbon is favoured by low free cyanide.
