What Is Copper Used For In Minecraft: You Need to Know
Copper ore (or raw copper) is smelted into copper ingots like any other metal ore – by putting the raw copper in a furnace. One piece of raw copper will give you one copper ingot. You can smelt copper twice as fast using a blast furnace – which is a key item for players who like to work with metal!

Copper Ore - an overview | ScienceDirect Topics
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.
Smelting – Minecraft Wiki
Smelting is a method of obtaining refined goods from raw materials by heating in a furnace, blast furnace, smoker or campfire. For example, raw iron can be smelted to produce iron ingots using coal as fuel. Like crafting, smelting uses recipes to determine what item is produced, but its recipes are simpler. Smelting also yields experience. The furnace, blast furnace, and smoker share a similar ...
