· Some of the mineral phases can immobilize the antimony and will reduce its leaching during weathering. Mineral phases such as FeSb 2 O 4 (schafarzikite) and FeSbO 4, because of their low solubility (<1 ppm), can be used as suitable candidates for the precipitation and immobilisation of antimony present in various mining effluents
