en.Wedoany.com Reported - Southwest Copper's comprehensive resource recovery project for high-bismuth lead anode slime produced its first batch of crude bismuth alloy on May 28, marking the full integration of the project's core process flow and its entry into the trial production phase.

The project was launched on October 10, 2025. During construction, Southwest Copper prioritized safety management and quality control, coordinating design, civil engineering, installation, and commissioning efforts. Through multi-party collaboration, the construction period was shortened. On May 2, 2026, the installation of the refractory lining for the project's core equipment, the bismuth converter, was completed. The construction team installed over a thousand specially shaped refractory bricks with millimeter-level precision. Subsequently, Southwest Copper, together with multiple participating units, completed furnace drying and curing, equipment joint commissioning, process verification, and personnel training. On May 27, the system began feeding materials, with stable operating parameters, confirming the reliability of the process design and equipment installation.

The production of the first batch of crude bismuth alloy achieved the separation and recovery of valuable metals such as bismuth, gold, silver, and antimony from the anode slime. Once operational, the project will enhance Southwest Copper's industrial layout of "resource development + recycling and recovery," improve the comprehensive utilization rate of rare and precious metal resources, extend the industrial chain, and revitalize secondary renewable resources.

Southwest Copper plans to continue optimizing equipment commissioning, production processes, and personnel skills to promote stable and high-yield production, enhance green manufacturing levels, and establish a benchmark for comprehensive rare and precious metal recovery projects.
