ACD-800A Macroporous Chelating Resin for Gallium Extraction
The ACD-800A macroporous chelating resin is specifically designed for extracting gallium using acid methods. This advanced resin enables efficient enrichment of metallic gallium ions from alumina mother liquor prepared by the Bayer process, offering significant advantages in cost, energy consumption, and operational efficiency.
Manufactured from polystyrene and acrylonitrile copolymer, ACD-800A features specialized functional groups with high affinity and selectivity for gallium ions (Ga³⁺). Unlike conventional ion exchange resins, it operates through coordination chemistry (chelation) principles, providing superior performance in gallium recovery applications.

Usage Methods
Resin Pretreatment (Laboratory Method)
Install resin column (effective size: φ25mm * 300mm), transfer measured resin volume soaked in pure water into column
Resin filling volume: 25-30 mL (1/4 to 1/3 of resin column)
Activate resin: rinse with pure water until effluent is clear, then drain; immerse in 5.0 mol/L NaOH solution
Maintain 2-3 cm liquid level of NaOH solution above resin layer
Activation completes after 24 hours (resin volume expands to approximately 1.3 times)
Resin Adsorption (Laboratory Method)
Operating flow rate: 1-5 BV/h
Operating temperature: ≤ 40℃
Precautions
Avoid bubble generation in resin bed layer to prevent cross-flow and maintain optimal performance
Prevent bacterial contamination by thoroughly cleaning resin with clean water after use to remove accumulated impurities
Regeneration Steps
Pressurization: Remove remaining material in resin column by pressure
Water washing: Wash resin with 2-4BV pure water at 2BV/h rate
Distillation regeneration: Perform using 4-6BV of 5% H₂SO₄ solution at 1-1.5BV/h rate
Acid washing water: Wash with 2-4BV pure water at 2BV/h flow rate
Activate resin: Activate with 2BV of 5.0 mol/L NaOH solution at 2BV/h rate, then proceed to next adsorption cycle
Resin Storage
Maintain proper moisture content during storage; prevent resin from drying out
If resin becomes dry, soak in saturated salt water for gradual expansion, then slowly dilute salt concentration
Prevent freezing or overheating; optimal storage temperature: 5-40℃
For temperatures below 5℃, use salt water soaking for freeze protection
For temperatures above 40℃, store indoors in dark location
