Copper Mining and Processing Processing of Copper Ores Iron Ore Sedimentary Rock Pictures Definition More

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of pure copper called cathodes which will ultimately be made into products for everyday useWhat is Iron Ore Used For The primary use of iron ore is in the production of iron Most of the iron produced is then used to make steel Steel is used to make automobiles locomotives ships beams used in buildings furniture paper clips tools reinforcing rods
