Metal and iron ore processing

iron-ore mining and its tailing wastewaters usually show high levels of dissolved ions and particulate suspended matter, thus changing the water chemistry (Holopainen et al. 2003) and the bioavailability of metals. This study aimed to identify the effects of iron-ore mining and processing on metal bioavailability in tropical
