• Iron ore mining and dressing tecscience

    Iron ore processing. After the iron ore has been prepared by crushing and grinding during ore extraction, the ore is actually processed. The aim of this is to reduce the undesirable high proportion of admixtures to a desired minimum in order to increase the iron content. This is done by processes such as flotation or magnetic separation
