Copper ore is a mineral block found underground. It's one of the most common, and weakest mineral that can be used to craft tools and armor. Copper ore requires a stone pickaxe or better to mine, and it will drop between one and three copper ore items, which are smelted three at a time to get a...
Sep 12, 2018· Most copper occurs in ores and must be smelted, or extracted from its ore, for purity before it can be used. But natural chemical reactions can sometimes release native copper.
Copper oxides are more abundant near the surface, but are considered lowgrade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper. Although the processing costs are higher, .
