Guanma Machinery PGM Refining Equipment optimizes platinum group metals recovery, whether processing scrap automotive catalysts, electronic waste, jewelry alloys, mine concentrates, or chemical residues. With soaring global demand and declining ore grades, investing in advanced precious metal recovery technology is crucial for securing your supply chain security and maximizing returns from complex secondary materials.
Platinum Group Metals (PGMs), also known as Platinum Group Elements (PGEs), are rare and valuable, making their recovery historically important.
PGM refining refers to the process of removing impurities from crude PGM feed materials to produce pure metals or pure compounds.
Oxygen Enriched Side-Blown Furnace Process Flow
1. Pyrometallurgical Smelting
Pyrometallurgical Smelting: Includes slagging, collection, separation of base metals, and integrated environmental protection equipment.
2. Hydrometallurgical Leaching & Refining
Hydrometallurgical Leaching & Refining: Involves acid leaching, precipitation, filtration, reduction, solvent extraction, and other processes to isolate and purify the precious metals.
1: Pre-Treatment & Conditioning
Milling, sampling, roasting (organics removal), smelting (concentrate formation).
2: Primary Dissolution
Targeted leaching (Aqua Regia, HCl/Cl2, HCl/O2, Sulfuric Acid pressure leaching) optimized for specific feed and PGMs.
3: Solution Purification & Separation
Solvent Extraction (SX): Highly selective separation of Pt, Pd, Rh, Ir using proprietary reagents. Key for complex streams.
Ion Exchange (IX): Fine purification, especially for Rh, Ir, Ru, Os removal from base metals.
Precipitation/Cementation: Initial concentration or removal of impurities (e.g., gold, silver, base metals).
4: Individual Metal Recovery & Refining
Ammonium Salt Precipitation: Classic method for high-purity Pt & Pd (e.g., Ammonium Hexachloroplatinate).
Selective Reduction: Controlled precipitation of pure metal powders (e.g., Hydrazine for Pd).
Electrowinning: Direct recovery of pure metal cathodes from purified solutions.
Crystallization: For high-purity salts (e.g., Rhodium Chloride, Iridium Chloride).
5: Finishing
Calcination, reduction (H2), melting, and casting into ingots/granules.
Raw Material & Output
Applicable Raw Materials: Scrap automotive three-way catalysts, spent petroleum catalysts, industrial catalysts, electronic waste (e-waste), anode slimes, alloy scrap, ores (copper ore, lead-zinc ore, gold ore, etc.), and other PGM-bearing materials.
Final Products: High-purity Platinum (Pt), Palladium (Pd), Rhodium (Rh), Iridium (Ir), Ruthenium (Ru), and Osmium (Os) metals meeting industry standards, with recovery rates ≥99% and purity levels reaching 99.995% or higher.
