Magnetic Separation and Magnetic Properties of LowGrade Manganese

The relation between the magnetic separation behavior and magnetic properties of a lowgrade manganese ore was analyzed before and after treatment by direct reduction with coal It was found that raw ore with an initial average grade of 1039% Mn and consisting of diamagnetic and paramagnetic minerals can be concentrated by Jigging of the −28 +07mm size fraction of a friable, lowgrade manganese ore sample from Andhra Pradesh increased the Mn content of a concentrate by 7% to 8%, with an average recovery of 57% The jig concentrate was mixed with the unjigged −07mm size fraction and ground to −150 μm The sample was then subjected Beneficiation of lowgrade, highphosphorus manganese ores

Beneficiation of two different lowgrade Indonesian manganese ores
