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 ...

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 - an overview | ScienceDirect Topics

Elution of AM-2B resin is similar to that of Minix; but a longer elution time seems to be required (Bolinsky and Shirley, 1996).The process includes a series of elutions, contacting the loaded resin with different solutions. The elution flowsheet differs from plant to plant, and some of the steps described below are optional.

Electrowinning - an overview | ScienceDirect Topics

Operation of the electrowinning process differs depending on the elution procedure that is used. In the case of Zadra elution, where the electrowinning cell is in series with the elution column, the column and cell must be designed to elute and recover the gold by recirculation of the eluant until the gold content of the eluted carbon is low enough (<100 g/t) to be reactivated and returned to ...

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.
