Metallurgy & Processing | Hycroft Mining

The process methods applied to Ore Category 3 are covered by a pending patent application. Ore Category 1 (ROM ore) – lower grade ore with high cyanide soluble gold is routed directly as run-of-mine to the leach pad and cyanide leached to extract gold and silver. This accounts for 4% of the ore over the life of mine.
