Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock.

Due to the strong floatability of graphite, flotation is the most commonly used method of graphite beneficiation. Among them, crystalline flake graphite has the best floatability, followed by vein graphite; …
