Crushing : mined copper ore is crushed into very small pieces ; Grinding : crushed copper ore is ground into a powder; Concentrating by flotation also known as froth flotation or as ore flotation. Mining produce ores containing 2% or less of copper. Concentrating the ore by froth flotation can result in ores with up to 35% copper.
