Stamp mills are used by miners to crush valuable ore and extract the metals within them. Gold silver and copper are common metals that are found within ore and stamp mills allow these metals to be released from rock for further processing and refining.
Copper Mining and Extraction Sulfide Ores
Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.
Copper Ore Processing Methods
These ores respond to gravity concentration of the coarser particles of copper and the finer particles may be recovered by flotation or as at Calumet & Hecla Conglomerate mill the sand portion of the gravity- plant tails may be leached and the slime portion may be treated by flotation.
Copper extraction - Wikipedia
Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite and unwanted impurities such as silicate gangue minerals or other sulfide minerals typically minor amounts of pyrite sphalerite or galena.
WoW Classic Ore Farming Guide: From Copper to Thorium ...
One possible exception may be Bronze Bars (1 Copper Ore=1 Copper Bar; 1 Tin Ore=1 Tin Bar; 1 Copper Bar + 1 Tin Bar = 2 Bronze Bars).
