As you can imagine, if ores can form from igneous processes, then they can also form from metamorphic or sedimentary processes also. Metamorphic ores often contain lead, zinc, and silver, as well as some iron oxides. Sedimentary ore deposits include banded iron formations, and gold, platinum, zinc, tin,......
Discovering Metals— A Historical Overview
Thus, although copper knives served a purpose, they lacked the strength to serve as effective weapons. The discovery that copper could be obtained by heating covellite, malachite, and other bright blue stones or minerals was made between 4000 and 3000 These were primarily copper sulfide ores. An ore is a natural mineral that can be mined and...

Copper ore is mined in the X41 and Enterprise underground mines using traditional sublevel open stoping methods. Once the ore is loosened by drilling and blasting, it is mucked, crushed and hauled to the surface where it is put through the concentrating process....
Copper Statistics and Information USGS
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of lowgrade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode....

ore were mined, and these "natural ores" have all but been exhausted. Mining of the lowgrade iron formation, or chertmagnetite ores, began during the 1950s. At about 25 to 30% midrecoverable iron, these lowgrade ores are beneficiated and upgraded to highgrade iron ore concentrates with an iron content of approximately 65%....
