Metals for modern life4.72 Мб. Boliden has been conducting exploration and mining operations and producing metal since the 1920s.An important property of metals is their ability to be repeatedly recycled through smelting before being made into new products.
Initially, many metals were obtained through open-pit mining, and ore was primarily extracted from shallow depths, rather than through deep mine shafts. Around the 14th century, the growing use of weapons, armour, stirrups, and horseshoes greatly increased the demand for iron.
The list of environmental concerns that can be connected with rare earth elements is not a brief one. Throughout the cycle of mining processes that rare earth elements go through, there is potential for negative effects on the environment.
Copper mining wastes make up the largest percentage of metal mining and processing wastes generated in the United States. There is a broad range of TENORM concentrations in copper mining wastes. There is a broad range of TENORM concentrations in copper mining wastes.

Mining Waste Products. The types of waste materials generated are dependant upon the type of mining activity. Around the Fal Estuary there have been effectively three main types of mining activity: (1) the recovery of cassiterite from the river sediments (so called tin streaming or placer mining); (2) the underground and opencast mining for metal (hard rock mining); and (3) opencast mining for ...
