THE AGITATED TANK SYSTEM
The Chemical Leaching Stage plays a pivotal role in the recovery of precious metals from materials such as spent catalytic converters. This process directly influences the overall efficiency and yield of metal recovery, making it a critical step in the refining cycle.
Milled and Thermally Pre-Treated Material: The catalytic converter material is first milled and thermally pre-treated before being transferred to the leaching unit. This step ensures that the material is adequately prepared for effective leaching.
Vacuum Transfer System: A vacuum transfer system is used to move the material to the leaching unit. This ensures clean and loss-free handling of the material, which is crucial for maintaining efficiency and preventing contamination.
Chemical Solution: In the leaching unit, a specially formulated chemical solution dissolves all precious metals, including platinum, palladium, and rhodium. This solution is specifically designed to target and dissolve these valuable metals.
Agitation and Mass Transfer: The Chemical Leaching System consists of specially designed tanks that use mechanical agitation to maximize the contact between the black mass (processed catalytic converter material) and the leaching reagent. This ensures better mass transfer rates, homogeneous reagent distribution, and optimized metal dissolution.
Advanced Control Systems: The system is equipped with advanced automation and control systems that maintain precise control over essential factors such as:
Temperature
Pressure
Level
Mixer Speed
These controls are crucial for maintaining the efficiency, reliability, and safety of the process.
Temperature Regulation: Heat management is critical in the leaching process to maintain the ideal reaction conditions. The system incorporates:
External jackets
Internal coils
Heat exchangers
These components regulate the temperature during the leaching process, enhancing heat transfer and ensuring consistent performance. By maintaining optimal temperatures, the system prevents overheating, which can compromise leaching efficiency and safety.
High Leaching Efficiency: The combination of mechanical agitation, precise control, and effective heat management ensures high leaching efficiency and excellent recovery rates of precious metals.
