Study on Removal of Iron and Manganese from Mine Water by Method of Medicament

Abstract:

Use single and coexistence of simulated mine water contains Fe2+ and Mn2+ as processing object, the new NWMO medicament on Fe2+ and Mn2+’s removal efficiency, NWMO dosage, pH, reaction time and temperature on NWMO’s removal efficiency were investigated. When treated mine water only contains Fe2+, the appropriate conditions of the factors are that NWMO dosage/Fe2+ content=19:1, pH=5, room temperature, the reaction time is 10min, and the removal rate of Fe2+ is more than 80%; When treated mine water only contains Mn2+, the appropriate conditions of the factors are that NWMO dosage/Mn2+ content=22:1, pH=6, 35°C, the reaction time is 10min, the removal rate of Mn2+ is more than 60%; When the processing of Fe2+ and Mn2+ coexistence of mine water, the appropriate conditions of the factors are that NWMO dosage/Fe2+content=19:1, Fe2+ content/Mn2+ content=5:1, pH=6, 35°C, the reaction time is 10min, the removal rate of Fe2+ can be as high as 100%, and the highest Mn2+ removal rate can amount to 75%. In view of the current mine water quality characteristics that contains Fe2+ and Mn2+, the NWMO medicament is very suitable, and can achieve quick and efficient removal of iron and manganese.
