The ore is mined by open pit methods by The Hanna Mining Company. After preliminary screening at the mine, ore is conveyed by an 8300 foot long aerial tramway to a smelter located at the foot of Nickel Mountain. The smelter, 2000 feet below the mine level, is owned and operated by the Hanna Nickel Smelting Company. Ore is smelted by an adaptation of the Ugine process (36) in which ferrosilicon is used to reduce iron and nickel oxides in molten ore to ferronickel containing about 48 percent nickel.
