Carbon-In-Pulp (CIP); Carbon-In-Leach (CIL); Carbon-In-Column (CIC). Refractory ore processing methods almost always serve only one purpose, to treat ores that will not liberate their values by conventional cyanide leaching. The refractory ore treatment process is then followed by a conventional cyanidation step.

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 the pulp dissolves. When workers introduce small carbon grains to the tank, the gold
