Project Overview
Sichuan Precision Technology is proud to present our technical proposal for a modern, high-efficiency Copper Scrap Recovery Plant. This facility is engineered to transform a wide range of copper scrap into high-purity anode copper, ready for electrolytic refining. By implementing advanced pyrometallurgical technology, this plant offers a sustainable, economically viable, and environmentally compliant solution for the critical recovery of valuable copper resources.
Core Process Flow: From Scrap to Anode
Our integrated process ensures maximum metal recovery and high product quality.
1. Scrap Receiving & Preparation
Incoming scrap is inspected, sorted, and prepared.
A hydraulic shear processes oversized pieces for optimal furnace charging.
2. Smelting
Prepared scrap is charged into a Submerged Arc Furnace.
The furnace melts the material under a protective slag layer, separating pure copper from impurities.
3. Slag Handling
Impurity-rich slag is periodically tapped, granulated, and managed for safe disposal or further processing.
4. Fire Refining
Molten copper is transferred to a Rotary Anode Refining Furnace.
The two-stage refining process (oxidation and reduction) removes residual impurities like sulfur and oxygen, ensuring the final metal meets anode quality standards.
5. Anode Casting
The refined copper is cast into uniform anode plates using a computer-controlled Anode Casting Wheel.
Anodes are quenched, inspected, and stacked for delivery to the electrolytic refinery.
6. Off-Gas Treatment
A comprehensive system captures all process gases.
Gases are cleaned through a Baghouse Filter and Acid Gas Scrubber to ensure emissions meet stringent environmental standards.
Key Features & Technological Advantages
High Efficiency & Yield: Advanced furnace design and process control achieve a copper recovery rate exceeding 95%.
Fuel Flexibility: The system can utilize natural gas or other suitable reductants in the refining stage.
Environmental Compliance: State-of-the-art gas cleaning technology minimizes particulate and SO₂ emissions.
Operational Safety: Automated handling of molten metal and comprehensive safety systems protect personnel and equipment.
Product Quality: Produces consistent, high-quality anode copper plates ideal for subsequent electrolytic refining into high-purity cathode copper.
