A look at the underground mining process The Resolution Copper deposit lies more than a mile beneath the surface. The most viable way to recover this ore body is by going underground, using a process called block caving. Block caving is a proven mining method using advanced technologies. Here''s how it works. Ore, rock containing . Continued
Improved separation and refining procedures have become available for all of the precious metals. These commonly involve operations such as solvent extraction or ion exchange. They are being introduced either to replace procedures in the classical process or as part of completely
This report summarizes mining practices of a large number of metal mines in the United States and foreign countries. The adaptation of mining methods best suited to the various natural conditions in mines is discussed, and comparative costs are presented.
From the mining equipment used to the advancements made in mining technology, aluminum mining has progressed from primitive methods to the use of technologically advanced equipment and processes that promote a tremendous increase in aluminum production.

In 2005, only 17% of metal mines were underground operations (Raw Materials Data, Stockholm 2010) – but there are many instances where underground extraction of minerals is more costeffective than surface mining, typically when the given ore body is high grade or very deep.
Part C deliberates the surface mining methods, which consist of strip mining of coal, openpit mining, and stability of pit slopes. This publication is intended for mining engineers, but is also useful to students and researchers conducting work on the application of extracting and processing minerals.
Bauxite is the only ore containing 2025 percent of aluminium from where the metal is extracted and commercially produced. The open pit or surface mining process is carried in this case since bauxite is mostly found near surface areas where the layers of soil contain a mixed amount of various minerals, iron oxides and titanium dioxide.
