In terms of production volume, underground mines account for as much as 64% of overall zinc production, combined underground/open pit mines provide 21%, and the remaining 15% is sourced from open pit mines. Rarely is the ore, as mined, rich enough to be used directly by smelters; it needs to be concentrated. Zinc ores contain 5-15% zinc.
