(54) Title: IMPROVED PROCESS 
F (57) Abstract: The present invention relates to processes includ
Figure33 Iron ore slurry - 202 ing the step of electrochemically treating an iron mineral. The 
processes are for improving the grade of iron, producing a magnet
ic iron mineral, producing an iron oxide, or for removing hydrox
Hydrocyclone - 204 ide or water from the crystal lattice of an iron mineral. The present 
invention also relates to iron minerals produced by the processes.
