The Silver Coconut: Carbon versus precipitation for high silver ores

Whenever flowsheets are considered for treatment of silver ores, the conventional approach is in favour of a Merrill-Crowe processing circuit rather than CIL/CIP.

This is understandable when the historical development of CIP is considered.

The paper presented addresses the continuing debate on the use of carbon for silver recovery, and seeks to explain the origin of the Silver Coconut “myth.”
