In general, high-silica iron ore tailings are mainly composed of quartz, feldspar, chlorite and a few associated elements, while the SiO 2 content can reach above 70 11,12.This invention refers to a water-less extraction process to collect clay, silica and iron ore from tailings taken from tailings dams and deposits by drying, dry sifting, density separation, mechanical friction separation, air classification separation, milling and magnetic separation. This is achieved by using pieces of equipment arranged in sequential order, as follows a horizontal rotary ...The typical magnetite iron ore concentrate has less than 0.1 phosphorus, 3-7 silica and less than 3 aluminum. The grain size of the magnetite and its degree of comingling with the silica groundmass determine the grind size to which the rock must be reduced to enable efficient magnetic separation to provide a high purity magnetite concentrate.preconcentrating bulk ore sub-samples. Hence the air classifier was modified with the goal of producing 10-30 grams sa mples aiming to capture all of the high density metallic particles, tungsten in this case.
