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.Sedimentary Manganese - Mineral Deposit Profiles, B.C,,The manganese sediments often display a variety of textures, including oolites and sedimentary pisolites, rhythmic laminations, slumped bedding, hard-ground fragments and abundant fossils. "Primary ore" is commonly further enriched by supergene process.How to Extract the Manganese Ore?,In recent years, magnetic separation method has occupied an important position in manganese ore dressing, and various new types of magnetic machines suitable for coarse, media and fine particles are successfully developed.
