Assay Red Lead Powder

Assay Red Lead Powder – Fire Assay Flux Reagent | GLASSWORLD South Africa

Assay Red Lead Powder (lead tetroxide, minium, Pb₃O₄) is a specialised flux reagent used in fire assay procedures for the determination of precious metals including gold, silver, and platinum group metals (PGMs). Red lead powder acts as an oxidising flux during the fusion stage, promoting the collection of precious metals into the lead button and improving overall assay accuracy. Trusted by mining laboratories and assay offices across South Africa and sub-Saharan Africa.

Key Features

• Oxidising flux for fire assay – Promotes efficient precious metal collection during fusion
• High-purity lead tetroxide – Consistent composition for reproducible fire assay results
• Fine powder form – Easy blending with other fire assay flux components
• Compatible with standard fire assay fluxes – Integrates seamlessly into existing fusion charge formulations
• Available in bulk quantities – Suitable for high-throughput mining and assay laboratories

Applications

• Fire assay fusion flux for gold, silver, and PGM determination
• Oxidising agent in fire assay charge formulation
• Precious metal collection and lead button formation
• Mining and exploration geochemical analysis
• Assay office and metallurgical testing laboratories
• Mineral processing and quality control

Safety Notice: Red lead powder is toxic and contains lead compounds. Handle with appropriate PPE including gloves, safety goggles, and a dust mask or respirator. Avoid inhalation of dust. Follow all relevant MSDS, laboratory safety, and lead handling protocols.
