Separating Metals from Mud

 · But within the mine, maybe only 2 percent of the rock we mine is valuable mineral and the other 98 percent is waste. In order to do the separation between the valuable minerals and the waste minerals, we need to grind them very finely down to, let''s say less than a tenth of a millimetre before we can do the separation. This is called liberation.

Mining and Mineral Use | Earth Science

Surface mining allows extraction of ores that are close to Earth''s surface. Overlying rock is blasted and the rock that contains the valuable minerals is placed in a truck and taken to a refinery.

Rock Crushing methods and How to recover gold from Ores

So as you are crushing, stop and screen your material, removing any free gold which has already separated from the rock during your crushing that won''t go through your screen with your fingers. The coarser rock that won''t go through your screen can then be returned to the crusher for further work to break it down, and the fines won''t get in the way.

Boys over the age of about 12 would have the job of dragging mine carts of ore out to the surface (though in some levels, small ponies did this task).

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 (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
