Minerals and some other materials

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.
