Lead and Zinc Department of Energy. Process Overview Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface.

sulfuric acid to extract the lead/zinc. These processes can operate at atmospheric pressure or as pressure leach circuits. Lead/zinc is recovered from solution by electrowinning, a process similar to electrolytic refining. The process most commonly used for lowgrade deposits is heap leaching. Imperial smelting is also used for zinc ores.

Energy and Environmental Profile of the Mining Industry some mining districts, the lead or zinc is found in massive deposits and mined similar to coal.

The galena in the Upper Mississippi zinclead district often occurs in coarse masses in veins up to 1 meter thick and several 10's of meters long (Strong, 1877). Coarse crystals ("cog ore") are also common and are dominated by cube and octahedron.

You can see the massive lead and zinc sulphides in red, the deposit is underlain by sill that may be partially responsible for driving the hydrothermal system. Shells contain the high highest amount of boron of any rock type and this is leached out along with the lead and zinc, by dewatering fluids, it is then deposited just below the vent as a stock work of tourmaline rich veins.

The Mining, Quarrying, and Oil and Gas Extraction sector distinguishes two basic activities: mine operation and mining support activities. Mine operation includes establishments operating mines, quarries, or oil and gas wells on their own account or for others on a contract or fee basis.
