Abstract

Abstract

The Sulfatization of manganese ore from Dongxiangqiao Region was investigated in a small quartz reactor with synthetic gas mixture of air and sulfur dioxide. The influence of temperatu re, reaction time, fineness of the ore, addition, concentration of sulfur dioxide in the gas mixture, etc. On the recovery of Mn, Co and Ni was studied systematically. It is recommended that the ore be milled to 95%-200 mesh and pilletized with 2-3% sodium sulfate, heated for one hour at 400#: and two hour at 700# in the gas mixture and the cooled mass be digested with water. Under these conditions mentioned above, the recovery of Mn, Co and Ni was above 90%, 80% and 60% respectively.
