Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal

Longwall Mining EquipmentLongwall Mining Equipment Product Line Overview. Roof Supports Customized Design is the world leader in longwall roof support technology. In the early 1970s, demanding mining conditions in German coal mines set the stage for extensive R&D in roof support technology. Steeply inclined coal seams both thick and thin, weak roofs and massive sandstone roofs, soft floors, and geological

Silver processing | BritannicaSilver processing, preparation of the ore for use in various products.. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen.The lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000
Both open-stope and bench mining methods are used at Cannington, with approximately 3.3Mt of ore processed each year. The ore travels to the surface from depths of up to 620 metres (m) via two methods; either by a nine tonne capacity vertical shaft hoisting system or by 50t haul trucks. The ore is then stockpiled for processing.(PDF) SURFACE MINING METHODS AND Academia.edu is a platform for academics to share research papers.Cannington Silver and Lead Mine, Queensland Initial mining will be undertaken in the Southern Zone. Cannington's major economic sulphides are galena and sphalerite. The silver occurs mainly as freibergite but is also present in solid solution within galena. At the end of 2005, the orebody contained proved sulphide ore reserves of 18.0Mt grading 477g/t silver, 10.7% lead and 3.9% zinc Mining Equipment For Sale - Equipment TraderMining Equipment For Sale: 74 Mining Equipment - Find Mining Equipment on Equipment Trader.
