Why is it better to recycle copper? - ASM Metal Recycling
Cheaper than mining and extracting new copper. Although the cost of mining new copper is reportedly falling, it is still far cheaper to recycle old copper than it is to mine and extract new copper ore. The value of recycled copper is worth up to 90% of the cost of the original copper, so it certainly holds its value. Great for local economies
Copper Processing - istc.illinois.edu
The ore usually contains less than 1% copper and is often associated with sulfide minerals. The ore is ground, concentrated, and slurried with water and chemical reagents. Air blown through the mixture attaches to the copper, causing it to float to the top of the slurry.

Ore - Official A Township Tale Wiki
Iron [] Iron ore veins begin to spawn near the crystal layer (around level 15-20), so players typically begin to gather the two ores at the same time. Because of this, Iron and Crystal are both intermediate level ores. When spawned, iron ore veins have a scratched surface and dark, matte extrusions, and drop three Iron ore when broken.
