Gold Process Equipment

Gold Ore Processing. Carbon-in-pulp (CIP) consists of cyanide leaching and then absorption of gold from ore, which is considered a simple and cheap process. Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution. CIP plants are similar to Carbon-in-leach plants.

Liquid–Solid Separation in Gold Processing

The flowsheets in Figure 18.1, Figure 18.2, Figure 18.3 illustrate how liquid–solid separation fits into carbon-in-leach (CIL), carbon-in-pulp (CIP), and Merrill–Crowe circuits, respectively. In addition, heap leach, column leach, and gravity circuits also need to have liquids separated from solids, and there are many variations of the flowsheets presented.

Processing | Macraes Operation

By the time the rock particle reaches the last tank, 98.5% of the gold is recovered. At the same time, activated carbon (coconut husks) are pumped upstream through the tank system to catch the leached liquid gold. Once full of gold, the carbon travels to a gold desorption column designed to wash the gold out of the carbon.

Strategies For Optimisation of Gold Processing Plants

Effect of pH on Au Recovery in the Presence of 0.25% Stibnite (After Hedley & Tabachnick 1968) Extrapolating the above trend back to the ordinate axis we note that recovery is once again achieved at pH 8.9 but with the reservation that gold recovery will reduce somewhat, and cyanide consumption increase, as the free CN- ion is replaced by dissolved HCN at the lower pH.

Gold Cil/Cip Process

About Gold CIP. Gold CIP is one of the methods of gold extraction by cyanidation. It is a carbon adsorption process of monovalent gold cyanide [KAu (CN)2] after the cyanide leaching of gold-bearing materials. CIP usually applies in flotation gold concentrate, high argillaceous oxidized gold deposit, mercury mixing, and gravity separation tailings.
