Copper Ore to High-Purity Copper, and the .

To obtain high-purity copper, the ore is concentrated for processing by crushing and grinding it into a powder containing 20-30% copper. The concentrates are smelted and the sulfide minerals are partially oxidized to yield a layer of "matte", a mix of copper-iron sulfide and slag, and an upper layer of waste.

Wrought iron - Wikipedia

Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily welded.
