Did you know? Round Mountain grinds down its high grade ore to the size of a human hair to optimize gold recovery in the leaching process.
As a large tonnage open pit operation, Round Mountain uses conventional open-pit mining methods and recovers gold using four independent processing operations. These include crushed ore leaching (reusable pad), run-of-mine ore leaching (dedicated pad), milling, and the gravity concentration circuit. Most of the ore is heap leached, with higher grade oxidized ores crushed and placed on the reusable pad. Lower grade ore, ore removed from the reusable leach pad, and stockpiled ore that was previously leached are placed on the dedicated pad.
