Nickel processing

Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel …

Metal ore mining in Europe

Southeastern Europe is an interesting region for gold ore mining. In this sector, Bulgaria plays an important role in the EU. The Canadian company Dundee Precious Metals acquired the Chelopech Mine in 2003 and increased its ore output from 0.52 Mta to over 2.0 Mta. In 2017, the mine produced 197 684 ounces of gold (about 5600 kg).

Winning the Metal: Ore Mills of the West

Article By Gary Carter. Photos sourced by Western Mining History. Numerous articles and books have described the techniques to extract valuable metals from waste rock. One of the best books on the subject is Drills and Mills by Will Meyerriecks. Meyerriecks describes the process of extracting metals from waste rock as "winning the metal".

Mining

Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of …

Metal Ore

For most metals the process of changing from the ore form to the metal form is to use heat to drive off the oxygen and other components that have combined with the metal ore. Processing of the metal ore forces the electrons from other ions (oxygen, etc.) that are being removed by the process to attach to the outer shell of the metal ion to form ...
