Definition

1. Noun:
   • A mineral ore that is the primary source of zinc: "Blende" refers to a naturally occurring mineral, specifically zinc sulfide (ZnS), which is the most important ore for extracting zinc metal. It is also commonly known as sphalerite.

Usage

• "Blende" is a technical term used primarily in geology, mineralogy, and mining contexts. It is not commonly used in everyday conversation.
• It is typically used as a countable noun (e.g., , ), though it is often treated as a mass noun when referring to the ore in bulk.

Examples

• Noun:
  • The miners extracted a rich vein of blende from the mountain.
  • Zinc is primarily obtained from the processing of blende.
  • Under ultraviolet light, some specimens of blende can fluoresce.

Advanced Usage

• "Black Jack": An old miner's term for dark-colored, iron-rich sphalerite (blende).
  • The prospector was excited to find a seam of Black Jack in the old mine.
• In metallurgy, "blende" specifically denotes the raw zinc sulfide ore before it is roasted and processed to produce zinc oxide and then metallic zinc.

Variants and Related Words

• Sphalerite (n): The more precise mineralogical name for "blende." While "blende" is the traditional mining term, "sphalerite" is the name used in scientific classification.
  • The geologist identified the crystal as sphalerite, not galena.
• Zinc Blende (n): A fuller term sometimes used to specify the zinc ore, distinguishing it from other minerals historically called "blende" (like "hornblende").
  • The zinc blende from this region is particularly high grade.

Synonyms

• Sphalerite: The scientific synonym for blende.
• Zinc sulfide ore: A descriptive synonym highlighting its chemical composition and purpose.

Notes on Different Meanings

• The standalone word "blende" almost exclusively refers to zinc sulfide (sphalerite). However, it is a component of the name for other minerals (e.g., hornblende, a silicate mineral). These are distinct substances and should not be confused with zinc blende.

Noun

1. an ore that is the chief source of zinc; consists largely of zinc sulfide in crystalline form
