Leaching in Metallurgy and Metal Recovery
Autoclave Leaching. 4) Autoclave Leaching Higher temperature and pressure are used to enhance the rate of the reaction. This aggressive method of leaching is typically used for ores and concentrates that are not amenable to atmospheric leaching such as sulphides. Each variation of leaching plays an important role in mining and metal recovery

Sol-gel processing differs from other chemical processes because of its relatively low processing temperature. This makes the sol-gel process cost-effective and versatile. In spraying processes the flow of reactants (gas liquid in form of aerosols or mixtures of both) is introduced to high-energy flame produced for example by plasma spraying

How Are Emeralds Mined LEAFtv
Open-Pit Mining. One way to mine emeralds is through the open-pit method. Workers dig a large pit about 12 meters deep and then blast the surface with water to reveal mineral-bearing rocks. In the open-pit mining method a lot of waste rock must be hauled away. The mining area is literally shaped like a pit that can hold equipment and workers.
