For all samples, the main tailing minerals were quartz and hematite, with minor quantities of magnetite (up to 2 wt.%) and goethite (up to 4 wt.%). Therefore, the hematite content varies between 13 and 58 wt.%, lowering as the distance from the end of the slurry pipeline of the processing plant increases.
