The output is calculated having full stamina at all times. It should be noted that you will be getting sedimentary geodes while mining. The geodes can later be opened to retrieve spirit shards and different gems.Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.Copper Ore an overview ScienceDirect Topics

Minerals Special Issue : Recent Advances in Copper Ore
The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary.Valheim copper ore creates a clearing in the Black Forest. Looking closely at the stone surfaces, you will spot slivers of copper seams running through the stone. If you’re uncertain, you can mouse over the stone surface.
