Feb 24, 2015· A significant fraction of iron ore used in steel production comes from magnetite deposits. Magnetite iron ore requires significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot of energy. This article investigates eco-efficient alternatives for the process design for magnetite iron ore.
Fine and Coarse Iron Ore Beneficiation – An Evaluation into Global Technologies and Techniques L M van Niekerk1 1. Senior Process Engineer, DRA Pacific, PO Box 1283, West Perth WA 6005.

Ore Grinding Mills are used for the fine grinding as the last step in the reduction of an ore prior to concentration (gravity or flotation) or cyanidation.Practice varies, depending upon the type of ore and the amount of reduction required. In addition, some of the older properties continue with methods that perhaps are not considered the best in light of recent improvements but that .
A third ball mill takes a split of feed from each module to assist maintaining a target product size. Both modules are fed from the same primary crushing circuit via a Coarse Ore Stockpile (COS) which provides surge capacity. The grinding circuit is designed to produce a product size suitable for the downstream froth flotation process.
