主　　题：high ferrous manganese spar manganese recovery ratio filtration time 

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