Extracting Mining From Their Ores

mining methods 101 how the metals we need,jul 06, 2016 once the ores have been excavated, the metals themselves must then be extracted from the ore, a process that depends on the metals reactivity, according to bbc. highly reactive metals such as aluminum, for example, can be isolated using an electric current in a technique known as electrolysis..mining and extraction oxide ores processes,education resources. copper mining and extraction oxide ores. copper is refined from ores in the ground, either through underground or open-pit mines. most of the copper ores mined today are oxide or sulfide ores. extraction of sulfide ores is covered in more detail in copper mining and extraction sulfide ores (1114), but is introduced here because an important by-product.
