For the highgrade manganese ores with lower iron content, even though all of the iron elements are dissolved into the solution, the iron ion concentration of the solution is still low. On the contrary, as for the FeMn ores with high iron content, the iron ions concentration of the solution is high even if the iron leaching efficiency is only
Manganese Ores. Some manganese minerals and mineraloids are considered "primary ores," because they are rich enough in manganese to be of ore grade. Others are "secondary ores." These occur in zones where the original manganese content of the sediments has been naturally enriched by younger geologic processes.
