The hydrometallurgical strategy of extracting Mn from low-grade Mn ores has attracted attention for the production of electrolytic ,manganese, metal (EMM). In this work, the reductive dissolution of low-grade MnO 2 ores using toxic nitrocellulose acidic ,wastewater, (NAW) as a reductant was investigated for the first time. Under the optimized conditions of an MnO2 ore dosage of 100 g·L ...

oygen. Oxygen is one of the most abundant elements found in Nature. In its molecular form O 2, oxygen or "dioxygen" is a colourless gas that is relatively insoluble in water (see characteristic constants of gases).. As demonstrated by the oxidation reduction equations, the oxidising capacity of oxygen is heavily dependant on pH and low compared to other oxidants used.

The laterite-coating ,manganese dioxide, nanoparticle material (M2) prepared by the immersion method was used for the efficient removal of methylene blue (MB) from aqueous solution. The adsorption and heterogeneous Fenton catalytic oxidation experiments of M2 were investigated by changing the effective factors such as time, pH, amount of M2, and concentration of MB.
