Gold and Silver Leaching by Cyanidation

The first is due to spills and leaks on account of poor launder design and tank spillages. Losses also occur when it is necessary to dump agitators, classifiers or thickener tanks, due to power failures or mechanical difficulties. ... How Alkalinity (pH) Impacts Silver and Gold Leaching. To reduce the amount of cyanide destroyed, lime is added ...

settling out, bogging the tanks. Agitation also ensures that the gold cyanide complex ions forming on the surface of a gold particle are removed into the wider solution to allow 'access' on the gold particles' surface for more unreacted cyanide ions to leach more gold from the particle. Temperature Higher temperatures will increase the ...

Gold Ore Tank leaching vs. Vat leaching

In tank leaching the ground, classified solids are already mixed with water to form a slurry or pulp, and this is pumped into the tanks. Leaching reagents are added to the tanks to achieve the leaching reaction. In a continuous system the slurry will then either overflow from one tank to the next, or be pumped to the next tank.

Continuous Gold Leaching and Tanks Short-Circuiting

Assuming a series of 100-ton tanks and a flow of 10 tons per hour, then approximately 1 ton out of the 10 tons flowing into the first tank will pass out immediately untreated into the second tank of the series: one-tenth of a ton per hour of this original pulp will pass directly from the second to the third tank and so on in diminishing ...

The document describes a study that used response surface methodology to optimize vat leaching parameters for gold recovery at small scale mines in Tanzania. The parameters investigated were cyanide concentration, slurry pH, and particle size. Using a central composite design, the study found that maximum gold recovery of 83% could be achieved with a cyanide …

Pachuca Tank

In some Pachuca tanks, air is allowed to rise in a free two-phase flow jet to the surface of the slurry so a natural circulation pattern is set up in the pulp. In other tanks an axially located draft tube, typically 0.5 m (20 in.) in diameter, carries a buoyant air-slurry dispersion from the bottom of the tank to the surface of the slurry.
