Lead and Zinc

6.1.1 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. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Antimony Statistics and Information

Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature.

Extraction of Zinc: Process, Methods, Diagarm, Examples

 · The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

Zinc

 · Commodity Zinc is a brittle, whitish metal used in a wide range of industries, most familiarly as a galvanizing material for steel. Known and used for millennia, it was named "zinc" in the early 1500s by Paracelsus, a Swiss physician and philosopher. The name was derived from "zinke," a German word for "fork tooth," referring to the form zinc often took when smelted.

Garpenberg (Fig. 17) is considered the most productive zinc underground mine in the world. In 2017, the mine output was 2.63 Mta of ore, with lead, copper, gold and silver being produced in addition to zinc. The Tara Mine in Ireland is Europe''s largest zinc mine. The ore is extracted there from a depth of about 1000 m (Fig. 18).

ABB Mine Hoisting System at Pyhäsalmi Mine

Mining Ltd) discovered the zinc/ copper ore deposit with reserves of over 30 million tonnes in 1958. Open-cast mining started in 1962 and continued until 1976, when it was switched over to underground mining. ABB supplied the mine hoist system. The shaft depth was then only about 660 metres but was later extended to 1,000 metres.
