Because a high zinc content would result in high leaching activity of zinc and inefficient vanadium solution, a zinc content in the solution below 100–125 g/L was preferable. The addition of manganese-dioxide-containing materials in the mill or, if necessary, in a leaching stage, reduced the reduction of the vanadium pentoxide V 2 O 5 to V 2 O 4 by absorption of iron from the steel balls in
