Description

Arsenopyrite CAS NO 1303-18-0 is an iron arsenic sulfide mineral and the most common arsenic-bearing mineral. It serves as a primary source of arsenic and is a significant ore of gold in certain deposits. This material is essential for metallurgical research, geological studies, and specialized industrial applications where its unique chemical composition is required.

Application

• Metallurgical Processing: As a primary ore for the extraction of arsenic metal and as a source of gold in refractory gold ores.
• Geological & Mineralogical Research: Used in academic and industrial research for studying ore genesis, mineralogy, and geochemical processes.
• Reference Standard: Serves as a certified reference material (CRM) for analytical laboratories conducting assays and environmental testing.
• Specialty Alloy Precursor: Provides arsenic for the production of specific lead and copper alloys to enhance hardness and corrosion resistance.
• Semiconductor Research: Investigated in material science for its potential properties in specialized electronic applications.
• Historical & Educational Collections: Supplied to museums and educational institutions for display and teaching purposes.

Quality Control

Our Arsenopyrite is sourced and processed under strict quality protocols to ensure batch-to-batch consistency and material integrity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as mineralogical purity, elemental composition, and particle size distribution where applicable. Quality is verified against in-house specifications and relevant geological reference standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to the nature of sulfide minerals, long-term storage in humid conditions should be avoided to prevent surface oxidation.
