Screening is an important step for dry beneficiation of iron ore. Crushing and screen­ing is typically the first step of the ore beneficiation processes. In the majority of the ores, valuable minerals are normally inter-grown with gangue minerals, so the minerals need to be separated in order to be liberated.

The purpose of beneficiation is to concentrate the ore mineral physically and chemically suitable for subsequent applications. The gravity concentration is a well-established and widely accepted technique for chrome ore beneficiation due to the density difference between the chromite mineral and other associated gangue-bearing minerals. The ...

The beneficiation of low-grade iron ores is a key research and development topic in the mineral processing industry. The gradual exhaustion of high-grade iron ore reserves, and rising consumer iron and steel demand globally necessitate efficient low-quality iron ore beneficiation to meet steelmaking quality requirements.
