| Abstract: | The reduction of the acidic leaching solution of cinder by pyrite concentrate and its mechanism was studied.Results show that the reduction degree of Fe~(3+) in the acidic leaching solution can reach 96.5% on the following conditions: Fe~(3+) concentration is 1.1 mol/L,liquid-solid ratio is 3∶2,90℃,stirring speed 500 r/min and reaction time 3h.The reaction order of Fe~(3+) is 1.66 and the apparent activation energy is 60.26 kJ/mol. |
