Why Is Ore Crushed Before Any Chemical Process Is Attempted

Jan 11, 2021

The ore An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding The ore is crushed, then ground into powder. Concentrating The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting This is where the chemical reactions start
