Although the era of CIP commenced in the late 1970s, the use of carbon for the recovery of gold was recognized and practiced much earlier. Davis (1880) patented the use of wood charcoal for gold recovery from chlorination leach liquors, with this process subsequently used at Mount Morgan, Australia in the early 1890s. Johnson (1894) patented the use of wood …
