The Mining Process – Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

Extracting Gold | HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to ...

Fidelity bust gold leakage syndicate | The Sunday News

Carbon Stripping – Denver Mineral Engineers

carbon as a sodium or calcium/gold cyanide ion pair (2) is desorbed from the carbon by a reversal of the adsorption kinetics. Gold is recovered from the pregnant strip solution by electrowinning onto steel wool. The gold depleted solution is then reheated and recycled to the carbon bed for reuse (see Figure 1).

Major Mines & Projects | Musselwhite Mine

Loaded carbon from the first tank (CIP #1) is scalped from the slurry over a screen and forwarded to the elution circuit to remove the gold. This elution step produces a concentrated solution of gold that is sent to the electrowinning circuit for gold recovery. The barren solution from electrowinning is recycled for reuse in the elution circuit.

Elution - Wikipedia

The "elution time" of a solute is the time between the start of the separation (the time at which the solute enters the column) and the time at which the solute elutes.In the same way, the elution volume is the volume of eluent required to cause elution. Under standard conditions for a known mix of solutes in a certain technique, the elution volume may be enough information to identify solutes.

During this stage a 2% caustic/3% cyanide solution mixture is re-circulated through the loaded carbon in the elution column until such time as a predetermined "top of column" temperature is reached. By this time most of the gold and silver on the carbon will have been desorbed into solution and both the carbon and the solution will have reached an optimum temperature for the subsequent ...

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.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.
