added during the leach (carbon-in-leach), or after leaching (carbon-in-pulp). Once the dissolved gold is removed from the solution, the mill tailings and resulting "barren solution" are pumped to the tailings impoundment. The gold is chemically stripped from the carbon, electrowon from the solution, and melted into impure bars, called doré.

The price of carbon offsets varies widely from <$1 per ton to >$50 per ton. The price depends on the type of carbon offset project, the carbon standard under which it was developed, the location of the offset, the co-benefits associated with the project, and the vintage year. Campuses may obtain a lower price per offset for larger volume purchases.

Next, mill operators thicken the slurry with water to form pulp and run the pulp through a series of leaching tanks. Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in ...

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.

In slurry systems, there is a general trend towards the use of carbon-in-leach (CIL) as opposed to leaching and carbon-in-pulp (CIP). This is still a matter of debate in the industry, but many plants which have used CIL have found that lower capital costs from fewer slurry tanks more than offset additional carbon handling as a result of lower ...
