Sphelite ACD-800A Gallium Extraction Chelating Resin 0.3-0.6mm Macroporous Beads

Product Introduction

Sphelite ACD-800A is a macroporous chelating resin built on a styrene-acrylonitrile copolymer matrix. Special functional groups with high affinity and selectivity for gallium ions (Ga3+) are grafted onto the polymer backbone. Its working mechanism relies mainly on coordination chemistry (chelation) rather than simple ion exchange, enabling low-cost, low-energy and high-efficiency selective enrichment of gallium from Bayer-process alumina mother liquor.

Technical Indexes

Key Applications

• Selective recovery of gallium metal ions from Bayer-process alumina mother liquor.
• Hydrometallurgical enrichment and purification of gallium (Ga) resources.
• Low-cost, low-energy alternative to solvent extraction for gallium recovery.

Operating Conditions

Pre-treatment: Rinse resin with 1-2BV pure water.

Adsorption Conditions: Suspended solids (SS) ≤ 1 ppm.

Regeneration:

• Regenerants: 4-6BV 5% H2SO4 and 2BV 5.0 mol/L NaOH
• Concentration: 5% H2SO4, 5.0 mol/L NaOH
• Flow rates: 1-1.5BV/h (H2SO4), 2BV/h (water & NaOH)
• Rinse resin with 2-4BV pure water after acid elution prior to NaOH activation

Storage

Storage temperature shall not exceed 90°C; store above 0°C in wet state. Keep the package sealed to prevent water loss. If the resin dries out, soak it in ethanol for about 2 hours, wash with clean water, then repackage or use. Prevent the beads from freezing and cracking in winter; if frozen, melt slowly at room temperature.
