Fixed Copper Refining Furnace

The Fixed Copper Refining Furnace is a traditional chamber-type flame furnace widely used in copper fire refining.

In this furnace, heat transfer occurs not only through flame reflection, but more importantly through radiant heat from the furnace roof and walls, ensuring effective thermal efficiency during refining.

Due to its fixed furnace body, key operations such as slag removal, oxidation, and reduction are carried out through manual direct operation, making it a mature and proven solution with high industry penetration.

PRS supplies Fixed Copper Refining Furnaces engineered for stable operation, adaptable fuel options, and reliable copper quality across various refining applications.

The Fixed Anode Furnace operates as a stationary chamber furnace:

• Heat is generated by flame combustion and transferred through:

1. Flame reflection
2. Radiation from furnace roof and side walls

• Molten copper refining is completed through:

1. Manual slagging
2. Oxidation (air blowing / intubation)
3. Reduction operations

• The furnace remains stationary throughout the refining cycle

This classic design ensures process simplicity and operational reliability, especially for plants prioritizing cost control and raw material adaptability.

PRS Fixed Copper Refining Furnaces support multiple fuel types to suit different site conditions:

• Natural Gas (NG)
• Liquefied Petroleum Gas (LPG)
• Light Diesel Oil (LDO)
• Fuel Oil (FO)
• Coal Gas

The Fixed Copper Refining Furnace can be used for producing:

1. Copper Anode Plates
2. Copper Anode Ingots
3. Low-Oxygen Copper Rods

It is suitable for refineries processing diverse copper feed materials with varying impurity levels.

Single furnace capacity: 15 tons to 180 tons per batch

PRS can provide customized furnace sizing and configuration based on production targets and plant layout.

• Simple and robust structure
• Low initial investment cost

• Long-term technical support

PRS helps clients balance investment cost, production stability, and operational safety throughout the furnace lifecycle.

Q1: What is the main difference between a Fixed Refining Furnace and a Tilting Furnace?
A: A Fixed Furnace remains stationary and relies on manual operations, while a Tilting Furnace discharges molten copper by tilting, offering better automation and environmental performance.

Q2: Is the Fixed Copper Refining Furnace suitable for low-grade raw materials?
A: Yes. Its strong adaptability makes it suitable for processing a wide range of copper feedstocks.

Q3: Can PRS customize the furnace capacity and fuel type?
A: Yes. PRS provides customized design based on capacity requirements, fuel availability, and site conditions.

Q4: What safety measures does PRS recommend for fixed furnaces?
A: PRS focuses on optimized tap-hole design, refractory selection, and operational procedures to reduce leakage and improve safety.
