Low grade phosphoruscontaining iron ore (LGPIO), a raw and wasted industrial solid material was used as an adsorbent to remove Cu(II) ion from wastewater. The effects of initial pH value, adsorptive time, initial Cu(II) ion concentration, adsorptive temperature and LGPIO dosage on the Cu(II) ion removal efficiency were studied. The results show that the Cu(II) ion removal ...

The leaching kinetics of highphosphorus iron ores in HCl solution was investigated. The effects of temperature ranging from 27°C to 50°C, particle size from mm and HCl concentration from to mol·L1 on the leaching efficiency of phosphorus were determined. The dissolution rates are significantly influenced by the temperature and concentration of acid solutions.
