How to Make Copper: A Comprehensive Guide

While technologies have advanced, processes like smelting, froth flotation, and leaching have roots in ancient techniques. Modern smelting uses high temperatures to separate copper from other minerals, similar to historical methods. Froth flotation, developed in the early 1900s, is still used to concentrate copper ores.
