Low grade ores – Smelt, leach or concentrate?
Assessment of alternative processing routes Metals are generally extracted from ores by either pyrometallurgical or hydrometallurgical processing routes. The former involves smelting of the ore or concentrate at high temperatures, while the latter involves leaching the ore or concentrate at relatively low temperatures, including ambient.
Life cycle assessment of iron ore mining and processing
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.
