Process Obtaining Mines

How Can Metal Mining Impact The Environment American


Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in areas nearby.

Uranium Mining Overview World Nuclear Association


Uranium Mining In the last fifty years uranium has become one of the worlds most important energy minerals. It is used almost entirely for making electricity, though a small proportion is used for the important task of producing medical isotopes.

Silver Processing


By the 16th century, Spanish conquistadores had discovered and developed silver mines in Mexico, Bolivia, and Peru. These New World mines, much richer in silver, resulted in the rise of South and Central America as the largest silverproducing areas in the world. For the recovery of New World silver, the Patio process was employed. Silverbearing ore was ground and then mixed with salt, roasted copper ore,.

Gold Extraction Wikipedia


Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold.

Copper Extraction Wikipedia


Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
