Thus, at 5A the iron content in the concentrate is only 1.5% more than its content in the original ore. Iron content in the concentrate increases considerably with the further increase of the current strength because iron ore particles with a low magnetic susceptibility (ore aggregates) begin to separate in the technological process.
