What is Smelting
Raw Material: The fundamental raw material for smelting is the metal-bearing ore. This ore is typically crushed, processed, and sometimes concentrated before it is used in the smelting process. Ore Selection: The type and quality of the ore are crucial factors that impact the efficiency and quality of the smelting process. 6. Protective Gear

Extractive Metallurgy of Copper | ScienceDirect
Pure copper metal is mostly produced from these ores by concentration, smelting, and refining. About 80% of the world's copper-from-ore is produced by concentration/smelting/ refining of sulfide ores. The other 20% is produced by heap leaching/solvent extraction/electrowinning of oxide, and chalcocite ores.
