Characterization and beneficiation of iranian low-grade manganese ore
The mineralogical studies indicated that Charagah ore deposit contains approximately 17% pyrolusite, 78% calcite and 3-4% quartz. Pyrolusite as a main valuable mineral is found in the forms of coarse and fine pyrolusites. The coarse grains pyrolusite with simple texture is liberated at 180 microns. Another kind of pyrolusite with particle …
