manganite

Thân thiện

A geologist holds a sample of manganite in a rock collection.

Definition

1. Noun:
   • A black mineral consisting of basic manganese oxide; a source of manganese: Manganite is a specific, naturally occurring mineral. It is characterized by its black color and its chemical composition, which is primarily a hydrated manganese oxide. It is an important ore for extracting the metallic element manganese.

Usage Examples

• Noun:
  • The geologist identified the black, metallic veins in the rock as manganite.
  • This deposit is rich in manganite, making it a valuable source of manganese for industrial use.
  • Under the microscope, the manganite crystals showed a distinctive prismatic shape.

Advanced Usage

• Scientific Context: In mineralogy and economic geology, "manganite" is used precisely to refer to the mineral with the chemical formula MnO(OH). It is distinguished from other manganese ores like pyrolusite or rhodochrosite by its specific crystal structure and properties.
  • The study focused on the paragenesis of manganite alongside other oxide minerals.

Variants and Related Words

• Manganese (n): The metallic chemical element (Mn) for which manganite is an ore.
• Manganous (adj): Relating to manganese in its +2 oxidation state (though manganite contains manganese in the +3 state).

Synonyms

• Mineral ore (general category)
• Manganese ore (specific category)

Related Terms

• Pyrolusite: Another common black manganese dioxide (MnO₂) mineral.
• Rhodochrosite: A pink manganese carbonate (MnCO₃) mineral.
• Oxide mineral: The broader class of minerals to which manganite belongs.
