The Sound Is Relatively Small When The Ore Is Crushed

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.
