How The Egyptians Crushed Ores

Copper is separated from its ores by either a dry or a wet process. In the dry process (also called pyrometallurgical, from “pyro” for heat), the ore is first crushed to a fine powder called concentrate. Most of the crushed ore then passes through a desliming cone. Here worthless earthy material is dissolved in water and discarded.
