TL;DR: The work highlights the possibility of reducing manganese ore by walnut shell with microwave heating by identifying four stages identified by temperatures and investigating dielectric properties and thermochemical characteristics of mixtures of walnuts shell and manganes ore.

TL;DR: The microwave dielectric properties of five pyrolusite-biomass mixtures were measured by resonant cavity perturbation technique and the pyrolysis reduction characteristics were systematically investigated, highlighting the universal feasibility of the novel coupled method for mineral reduction.

TL;DR: The work highlights the feasibility of processing manganese anode mud by microwave heating, with excellent responsiveness to microwaves, and investigates the dielectric properties and thermal behavior of pure MnO2, CaSO4 and PbSO4 components.

TL;DR: Thermogravimetric analysis indicated biomass pyrolysis process for reduction of pyrolusite was divided into four phases identified by temperatures, and the strongest preferential orientation of MnO was appeared, with good crystalline structure and no MnO2 and FeO peaks detected.

TL;DR: In this article, a pilot-scale study was initiated to evaluate the enhanced effect of microwave heating on carbothermal reduction process of pyrolusite, and the results indicated that the non-conventional technology by microwave heating to reduce low-grade pyroxite is very promising and could be considered for full scale applications.
