  Characterizations on phase reconstruction ... - ScienceDirect

  202151 · Huge differences in hardness, magnetism, fusibility and cooling shrinkage of ferrites and silicates provided excellent mineralogical conditions for the successful grinding and magnetic separation of ferrites. Eventually, a soft magnetic manganese ferrite precursor with recoveries of 89.2 wt% iron and 85.6 wt% manganese was obtained.

  Mechanochemical synthesis of copper manganese oxide for …

  201541 · Abstract A series of copper manganese oxide catalysts have been prepared by mechanochemical grinding of carbonate precursors and tested for the low temperature oxidation of CO. It is shown that a 72 h grind time and heat treatment under oxygen is necessary to form active CuMn 2 O 4 for the conversion of CO to CO 2 at room …
