Many iron ore producers are facing challenging times processing crude material with rising levels of impurities and a volatile iron ore price. Beneficiation, particularly washing (scrubbing), can be the key to upgrading the ore to earn per shipped tonne. High end steel production at a low coke consumption level and a high productivity rate can only be achieved by using high quality.
