Recovery Process

The mineral processing operation at Jerritt Canyon is one of only three processing plants in Nevada that uses roasting in its treatment of refractory ores. Initially, Jerritt Canyon was designed to process oxide and mildly refractory gold ores. In 1989, the roasting circuit was added to the process for the treatment of highly refractory ores which are now being mined and processed at Jerritt Canyon.

The unit operations at the Jerritt Canyon processing plant are comprised of the following circuits:

Primary crushing;
Secondary crushing;
Fine ore drying;
Tertiary crushing;
Dry grinding;
Roasting;
Carbon-in-leach ("CIL") with cyanidation and carbon adsorption;
Carbon stripping;
Carbon reactivation;
Merrill-Crowe process using zinc cementation of gold and silver;
Precipitate refining;
Oxygen plant; and
Tailing impoundment.
