Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface. Sand can replace eroded coastline. Some uses require higher purity than others; for example sand used in concrete must be free of seashell fragments.

Nov 01, 2018 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).
The above pre-treatment stages can be changed based on ore mineralogy. For a complex Au–Ag ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at <38 µm.Diagnostic leaching was carried out to assess the nature of refractoriness [29].Depending on the results of the diagnostic test results, extraction strategies for gold
