Apr 25, 2018· These include gravity concentration, carbon in pulp (CIP), and carbon in leach (CIL). "The methodology selected is a function of the mineralogy of the ore. If the gold is associated with oxides, for example, it can be amenable to heap leaching. The grade also plays a key role.
Leached pulp and carbon are transferred in a counter current flow arrangement between a series of tanks, usually numbering 4 to 6. In the final tank, fresh or barren carbon is put in contact with low grade or tailings solution. At this tank the fresh carbon has a high activity and can remove trace amounts of gold (to levels below 0.01 mg/L Au in solution).
As a result of the depressed gold price, there is a worldwide trend towards low-cost heap-leaching operations. Heap leaching provides relatively low-grade, clear solutions from which the gold has to be recovered. In practice, carbon-in-solution (CIS) is generally used for the upgrading of the gold…

The carbon-in-pulp process is used to treat low grade gold and/or silver ores. The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. This is done to produce a feed suitably sized so that subsequent leaching is rapid.
These include gravity concentration, carbon in pulp (CIP), and carbon in leach (CIL). "The methodology selected is a function of the mineralogy of the ore. If the gold is associated with oxides, for example, it can be amenable to heap leaching. The grade also plays a key role.
3. Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.

information on gold carbon in leach plants . Carbon Adsorption In Recovery Of Gold From Cyanide Leach Solutions. It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years, and many papers have been written on the subject. ... with the explosion of heap leaching of vast quantities of low grade ...
The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton...
By replacing the Merrill–Crowe zinc cementation step, carbon-in-pulp (CIP) and carbon-in-leach (CIL) recovery provided a process that allowed the treatment of lower grade and problematic ores (e.g., high-clay ores), at lower capital and operating costs and higher metal recoveries.
Oct 24, 2014· Prof Eksteen also recommends it for future in-situ heap leach extraction projects, a process that is expected to make mining low-grade deposits in remote locations more viable.
Oct 24, 2014· It can also be used in a similar manner to existing gold refining processes such as carbon-in-leach and carbon-in-pulp. "In normal gold leaching you would leach …
