Abstract: Through the intersection of water treatment and metallurgy,a new energy-saving and environmental friendly process for simultaneous production of manganese and manganese dioxide via electrolysis by means of ion exchange membrane combination process as well as recovery of sulfuric acid is proposed to solve the problems in traditional manganese metal preparation method,such as single product,waste of resources and energy,and environmental pollution.When manganese and manganese dioxide are simultaneously produced,sulfuric acid is recycled to increase productivity and reduce energy consumption.It has been proved by experiments that this process has great practical application value.
