Synthesis of manganese ferrite from manganese ore prepared by

Subsequently the calcined manganese ore was ground and sieved resulting in 400 mesh powder. The manganese ore was then mixed with commercial Fe 2 O 3 powder at a ratio of 50:50 in weight percent. The mixture powder was milled using a planetary ball mill for 24 h and the balltopowder mass ratio was 20:1 with the rotation speed 300 rpm.
