Metal ore mining in Europe - Mineral Processing
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).

A buddle was used in the mineral mining industry to separate by sedimentation minerals from lighter rock dust in crushed ore (when extracting gold, silver, tin, lead and zinc). The running water and ore mixture was sluiced down the incline, using gravity to allow the heavier ores to lie as sediment at the base of the workings.

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.

Ores are the minerals from which metals can be extracted efficiently and profitably. A previous meaning limited the term ore to metallic mineral deposits, although it has since been expanded to cover non-metallics in some cases. Only roughly 100 of the more than 2,800 mineral species have been recognised as ore minerals.

History, Deposits, and Production of Zinc
The Extraction of Zinc from Ores. The most important mineral for zinc production is the so-called zinc blende (ZnS). This means that apart from zinc, the concentrate contains about 20 % sulfur. Additionally, zinc concentrates always contain iron, lead, and silver in varying proportions, because these elements often occur together in the ores. ...
