Reverberatory Furnace

The PRS stationary copper refining furnace is a reverberatory-type thermal processing unit purpose-built for scrap copper fire refining and recycled copper production. It is engineered to handle a full spectrum of copper scrap feedstocks, from clean grade 1 copper to mixed industrial scrap, delivering stable anode-grade molten copper for downstream casting or electrolysis.

Widely adopted in global copper recycling plants, this furnace stands out for its broad raw material compatibility, low operating cost and robust structure. PRS optimizes combustion system and refractory lining design for scrap processing scenarios, helping clients achieve higher metal recovery and lower energy consumption in recycled copper production.

1. Full Spectrum Scrap Compatibility

The furnace processes 100% scrap copper with widely varying forms and grades, including Barley, Berry, Birch, enameled wire, Candy and Clove. Its large chamber design and flexible heating control adapt to bulk scrap charging, and the refining process can be adjusted according to impurity content to ensure consistent output quality.
 

2. High-Efficiency Combustion System

• Multiple combustion configurations available: conventional high-temperature combustion, oxygen-enriched combustion and pure oxygen combustion
• Oxygen-enriched combustion for natural gas and LPG reduces fuel consumption by ≥40% compared with standard air combustion
• Compatible with natural gas, LPG, light diesel oil, heavy oil and coal gas to match local energy supply conditions
   

3. Durable Corrosion-Resistant Refractory Lining

The furnace is lined with premium Mg-Al-Cr bricks or spinel Mg-Al-Cr bricks on the hot face, specially selected for scrap copper refining conditions. This material offers excellent resistance to high-temperature slag corrosion and molten metal erosion, effectively extending lining service life and reducing frequent relining downtime.
 

4. Customizable Capacity Range

Single-batch capacity ranges from 15 to 120 tons. Furnace dimensions, charging port layout and combustion power can be fully customized according to plant floor layout, production scale and scrap charging methods.
 

5. Low Maintenance & Fast ROI

• Simple stationary structure with few moving parts, resulting in low failure rate
• Minimal auxiliary equipment required for basic operation
• Mature and easy-to-master refining process, reducing operator training cost
• Low initial investment enables fast project payback for copper recycling operations

The complete refining cycle for scrap copper follows the sequence below:

1. Scrap Charging: Copper scrap is loaded into the furnace chamber through the charging port, via forklift, charging vehicle or manual feeding.
2. Melting & Heating: The burner system heats the furnace, melting scrap through combined flame reflection and lining thermal radiation.
3. Oxidation Refining: Compressed air is injected into the molten bath to oxidize and remove impurity elements such as iron, lead and zinc.
4. Slag Removal: Floating slag generated during oxidation is raked out manually through the slagging door.
5. Reduction Operation: Reducing agents (wood, natural gas, etc.) are introduced to adjust oxygen content and bring copper purity to anode grade.
6. Tapping & Discharging: Refined molten copper is tapped through the tap hole and transferred to downstream casting equipment.

• Fire refining of various grades of copper scrap
• Recycled copper anode production for electrorefining
• Copper scrap regeneration and remelting in recycling plants
• Small and medium-sized secondary copper production lines
