Description

Chalcopyrite CAS NO 1308-56-1 is a naturally occurring copper iron sulfide mineral and a primary industrial source of copper. Its consistent composition and high copper content make it a critical raw material for reliable and efficient metal production. This mineral is essential for suppliers and processors in the metallurgical, mining, and chemical industries seeking a fundamental feedstock for copper extraction and related chemical synthesis.

Application

• Primary Copper Ore Processing: The predominant source for the extraction and smelting of copper metal.
• Sulfuric Acid Production: Used in the manufacturing process where sulfur dioxide, a byproduct of roasting, is converted to sulfuric acid.
• Catalyst Precursor: Serves as a raw material in the synthesis of catalysts for certain chemical reactions.
• Pigment and Semiconductor Research: Investigated for use in traditional pigments and as a material in photovoltaic and semiconductor research due to its unique crystal structure.
• Geological & Educational Standards: Used as a reference mineral in geological studies, mineralogy collections, and educational demonstrations.
• Ferrite Production: Can be a source of iron in the production of certain ferrite materials used in electronics.

Quality Control

Our Chalcopyrite is sourced and processed to meet stringent quality parameters for industrial use. Quality is assured through batch-specific analysis targeting key metrics such as copper (Cu) content, iron (Fe) content, and sulfide (S) composition. Certificates of Analysis (COA) detailing these specifications are available upon request to ensure transparency and compliance with your processing requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and oxidizing agents. As a mineral product, it is generally stable under these conditions, but protection from excessive moisture is recommended to prevent surface oxidation over extended periods.
