Description
1. Product Overview
Platinum Filter Cake is a high-value intermediate palladium/platinum group metal (PGM) material recovered from industrial refining and recycling processes. Its primary industrial use is as a concentrated feedstock for platinum refiners, catalyst manufacturers, and specialty chemical producers seeking to recover pure platinum metal. The key value proposition lies in delivering a consistent, assayable platinum content with low impurities, enabling cost-efficient downstream processing and reduced smelting losses. In a market defined by supply volatility and ESG scrutiny, Platinum Filter Cake represents a strategically important secondary source that de-risks PGM supply chains and supports circular economy mandates.
2. Key Specifications & Technical Characteristics
- Chemical Composition: Platinum (Pt) bearing filter cake; typical Pt content 15% – 35% on dry basis; balance comprises SiO₂, Al₂O₃, Fe₂O₃, and trace PGMs (Pd, Rh)
- Purity Level / Grade: Industrial/Refining Grade; deleterious elements (Pb, As, S, Cl) controlled to <0.5% total
- Physical Characteristics:
- Form: Moist filter cake / pressed solids
- Color: Dark grey to black
- Particle Size: D50 20-80 µm after drying
- Moisture: 25% – 40% w/w, adjustable per contract
- Bulk Density: 1.1 – 1.4 g/cm³ (as received)
- Packaging Options: 1 MT woven PP big bags with PE liner, palletized; or 25 kg HDPE drums; custom packaging available

3. Core Industrial Applications
- Primary Industries: Precious metal refining, autocatalyst manufacturing, petrochemical catalyst production, pharmaceutical & fine chemical synthesis, fuel cell and electrolysis component fabrication
- Specific Operational Use Cases: Direct feed for pyrometallurgical/hydrometallurgical platinum recovery circuits; re-pulping for leaching and precipitation; toll refining feedstock; catalyst precursor synthesis
- Performance vs Alternatives: Compared to spent catalyst or mixed PGM sludge, Platinum Filter Cake offers higher Pt concentration uniformity, lower gangue variability, and faster dissolution kinetics, reducing refining cycle time by 15-30%
- Efficiency / Cost Advantages: Reduces energy and reagent consumption in smelting due to pre-concentration; lowers working capital through predictable assay and settlement terms; minimizes handling of low-grade, high-volume waste streams
4. Competitive Advantages
