Description

1 LB Assay Silica 70 Mesh

The 1 LB Assay Silica 70 Mesh is a high-purity silica (SiO2) ingredient designed for assay flux and flux thinner used in melting and smelting gold and other precious metals. The 70-mesh size provides reliable flow and even distribution, helping to form stable slag and support accurate assay results. This silica is formulated to blend smoothly with common flux components, delivering consistent performance in metallurgical processes.

Key benefits include predictable performance, colorless operation, and compatibility with standard flux formulations. The silica’s stable composition minimizes impurities impacting assay readings and metal recovery.

• High-purity SiO2 for consistent assays
• 70-mesh size for uniform flux texture and flow
• Ideal ingredient of assaying flux and flux thinner
• Suitable for melting and smelting gold and other precious metals
• Chemically inert under high-temperature flux operations

Designed for reliable flux formulation, this silica powder blends with borax, soda ash, and other flux components to produce a dependable molten flux during refining. Exact composition is silicon dioxide (SiO2), supporting precise, repeatable assay results across batches.
