The ore used for all of the experiments was a limonitic ore from the Ivory Coast, which was provided by Xstrata. The composition of the ore was determined by X-ray fluorescence (XRF) and is shown in Table 1. Assuming that the iron was present as goethite, the composition was converted to an approximate mineralogical composition …

The Sydvaranger magnetite mine closed in 1996 due to low iron ore prices and was reopened in 2009. The flowsheet has remained more or less as in the old plant, based upon two grinding steps followed by magnetic separation. The magnetite is free of harmful elements and should be attractive on the high quality market. This requires a …
