Preparation of MnSO 4 from high ferrous manganese spar is studied by experiment.Problems in traditional ways,such as undesirable increasing of solution viscosity and difficulty in neutralization, are solved emphatically.Manganese recovery ratio can be increased by 5%～8% with the technology recommended.And filtration time is reduced by 1/3 of the traditional ways.
