The gold refining workshop includes alloy casting, punching, wet gold separation, anode plate casting, electrolysis, granulation, polishing, marking, weighing and gold system to realize fully automated production from gold mud to gold ingots to greatly reduce labor intensity. In the production process, manual intervention is only necessary in specific parts, such as gold mud loading, ingot casting, feeding and slag removal, and the rest is completed automatically. The workshop adopts the information architecture of ERP for enterprise, MES for management, DCS for operation and PLC for control to ensure efficient and stable production. DCS is based on Siemens Wincc technology and PLC is interconnected via ProfiNet bus interface to realize rapid adjustment of equipment. The whole system is also equipped with an unmanned workshop information interface for intelligent and automatic production in the future. This comprehensive solution not only improves production efficiency, but also ensures product quality and stability, meeting the high standards and requirements of modern gold refining.
