- How Is Sphalerite Ore Processed
Carbon paste electrodes made from sphalerite ore powder were processed for 2 h in Fe 2 (SO 4) 3, O 3, and O 3 + Fe 2 (SO 4) 3 system, respectively. Carbon paste electrodes are made using mineral powder, including residues and untreated sphalerite, homogeneously mixed and pressed with graphite powder and paraffin wax in a ratio of 7:2:1.
