HICLOVER Precious Metal Recovery Furnace

HICLOVER Precious Metal Recovery Furnace

(Controlled Low-Temperature Roasting/Ashing + High-Temperature Afterburner + Optional Quench Scrubber + Dry Ash/Wet Sludge Recovery + PLC Control)

The HICLOVER Precious Metal Recovery Furnace is a thermal pre-treatment solution designed for precious metal recovery workflows. It processes precious-metal-bearing materials―such as resins, plastics, oily residues, surface coatings, activated carbon/resin carriers, and e-waste intermediates―into recoverable ash, while maintaining controlled treatment of oil smoke, VOCs, and pyrolysis flue gas generated during heating.

A/B/C Process Structure

Stage A ― Controlled Roasting / Ashing

A gradual, low-temperature thermal process removes organics in a stable and controllable manner, producing dry, recoverable ash.
Ash is collected using movable high-temperature trays, enabling centralized collection and simplified downstream recovery handling.

Stage B ― High-Temperature Afterburner

A dedicated high-temperature oxidation stage ensures more complete destruction of oil smoke, VOCs, and cracking/pyrolysis gases, helping reduce odor, black smoke, and internal fouling, while improving overall cleanliness and operational stability.

Optional Stage C ― Quench Spray Scrubber

For higher cleanliness requirements, an optional wet treatment stage can be applied for rapid quenching + washing + demisting.
This section generates wet sludge for periodic discharge and can be re-ashed when needed to maximize precious metal retention.

Key Advantages

• Centralized recovery: dry ash + wet sludge capture to improve precious metal retention

• Cleaner operation: stable gas cleanup with reduced buildup and lower maintenance load

• Customizable capacity: chamber volume and throughput configurable to project needs

• Fuel flexibility: Diesel / Natural Gas / LPG supported

• PLC recipe control: temperature curves, holding time, airflow management, and safety interlocks

• Modular design: optional mobile/containerized configuration for fast installation and deployment
