Underground mining (hard rock)

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

Mine Tailings Ground Truth Trekking

Hazardous Properties. Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and

The Mining Process Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.


Dumont Nickel Mine, Quebec Mining Technology Mining

Dumont Nickel Project is a nickel sulphide (NiS) deposit lying in the AbitibiT233;miscamingue region of Quebec, Canada. The mine falls within the precincts of Launay and Tr233;cesson municipalities and is located approximately 15.5 miles (25km) northwest of the city of Amos, 37 miles (59km) northeast

TENORM Copper Mining and Production Wastes Radiation

Waste GenerationOres that contain copper in the U.S. are typically mined in large, openpits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.Uranium, which may be colocated with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice.

Nickel Ore Mining Process,Processing Nickel Ores,Nickel

When floatability difference happens to the various nickel elements in the raw ore, the nickel ore can be recycled from tailings after the copper and nickel did the mixing flotation. Copper Nickel Ore Flotation Process A basic principle of coppersulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore.


Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.


Although Minnesota has a long history of iron ore mining, sulfide mining for copper, nickel, and precious metals has never been attempted. Prices for some metals, including copper, reached historic highs in 2011, and some companies have sought to mine Minnesota's lowgrade sulfide ores.
