Iron ore – improving ore quality AusIMM Bulletin
Depending on the ore type, quality and its degree of disintegration, a washing and classifying plant can increase the iron content by two to five percentage points. Washing of fines below mm can also reduce silica, alumina, titan oxide, sulphur and phosphorous content (Krellmann, Hoppe and Grotjohann, 2008), which can lead to significant improvements. For example, decreasing the alumina
