Manganese-containing anode sludge is a common side-product in the electrowinning of zinc. The anode sludge consists mainly of oxidized manganese, but also lesser amounts of lead, calcium, and other minor metals. The impurities present in the anode sludge mandate new recycling strategies for its efficient use. This work demonstrates a In the present investigation results on the use of dried leaves as a reductant for manganese ore leaching is reported. A complete flow-sheet consisting of steps such as reductive acid leaching, enrichment of leach solution by recycling, iron removal and crystallization has been developed for the preparation of manganese sulphate Dried leaves — Novel reductant for acid leaching of manganese ore

Experimental validation showed that MnO2 was reduced stepwise to low-valence manganese oxides and manganese sulfate. The phase composition of the roasted products was complex, and MnS wasA comparative analysis on the recovery of manganese ore was also investigated under the optimal leaching conditions for two different reductants, iron sulphate (FeSO4) and iron powder.Reductive leaching of pyrolusite ore by using sawdust

Manganese dioxide is typically reduced to a bivalent state before being extracted; here, sulfur is considered an efficient reductant and sulfur–based reduction has been industrialized in China. In this study, the reaction mechanism between MnO2 and gaseous sulfur was investigated. Thermodynamically, the reduction of MnO2 by gaseous Using less expensive and more plentiful materials is bringing down the costs of daily commuters, saving nickel for higher-end, longer-range vehicles.

In our work, the preparation technique of manganese sulphate with high purity directly from low-grade rhodochrosite ore (containing 13.86% Mn) was studied and improved intensively. In detail, the repeated leaching of rhodochrosite with sulfuric acid was proposed herein to improve the solubility ofsolution of manganese ore, which will influence the produce of manganese sulfate. Solubility determinations of calcium sulfate, magnesium sulfate and manganese sulfate in water have been carried out from 273.15K to 373.15K. According to the basic data, a new method to remo2+ ve Caand Mg2+ impuritis in leaching solution has been put forward.IOP Conference Series: Earth and Environmental Science
