Standard Upgrade, A New Milestone for the Industry

On October 24, 2024, the Ministry of Industry and Information Technology of the People’s Republic of China officially released the newly revised series of hydrometallurgical electrode plate industry standards. These standards were initiated and drafted by Yunnan Daze Electrode Technology Co., Ltd. (hereinafter referred to as “Daze”), together with leading enterprises including Yunnan Chihong Zinc & Germanium Co., Ltd., Norin Mining Ltd., Henan Yuguang Zinc Industry Co., Ltd., and Danxia Smelter of Zhongjin Lingnan Nonfemet Co., Ltd. The new standards officially came into effect on May 1, 2025.

Since 2014, Daze has led the drafting of four key hydrometallurgical electrode plate industry standards: Anode Plate for Hydrometallurgical Copper Electrowinning YS/T 1089—2015, Cathode Plate for Hydrometallurgical Copper Electrowinning YS/T 1090—2015, Anode Plate for Hydrometallurgical Zinc Electrowinning YS/T 995—2014, and Cathode Plate for Hydrometallurgical Zinc Electrowinning YS/T 1088—2015. Over the past decade, these standards have played an important role in regulating industry development, improving product quality, and driving technological progress.

Strong Partnerships, Setting New Industry Benchmarks

With deep technical expertise and extensive practical experience in electrode materials, Daze worked closely with its partners to comprehensively revise and improve the existing standards.

In the field of copper electrowinning, Daze collaborated with Yunnan Chihong Zinc & Germanium Co., Ltd. and Norin Mining Ltd. to update Anode Plate for Hydrometallurgical Copper Electrowinning YS/T 1089—2024 and Cathode Plate for Hydrometallurgical Copper Electrowinning YS/T 1090—2024.
In the field of zinc electrowinning, Daze partnered with Yunnan Chihong Zinc & Germanium Co., Ltd., Henan Yuguang Zinc Industry Co., Ltd., and Danxia Smelter of Zhongjin Lingnan Nonfemet Co., Ltd. to revise Anode Plate for Hydrometallurgical Zinc Electrowinning YS/T 995—2024 and Cathode Plate for Hydrometallurgical Zinc Electrowinning YS/T 1088—2024.

This “l(fā)eading enterprises taking the lead, industry chain collaboration” model of standard formulation not only ensures the advancement and applicability of the standards, but also guarantees that the standards accurately reflect industry needs and technological trends, laying a solid foundation for their effective implementation.

The technical innovations in the new standards not only reflect the latest achievements in the industry, but also provide technical support for advancing hydrometallurgical electrode plates toward high performance, long service life, and low energy consumption. In particular, the newly added requirements for electrical conductivity and welding quality will significantly improve energy utilization efficiency during the electrowinning process, creating favorable conditions for nonferrous metal smelting enterprises to achieve energy-saving and emission-reduction goals.

Responsibility and Commitment, Serving National Strategies

As a primary contributor to industry standards, Daze has always embraced the mission of “first-class enterprises make standards,” regarding standardization as a key driver of innovation and development. Over the years, the company has continuously increased investment in R&D, established a high-level electrode material research center and testing laboratory, and built a strong team of standardization professionals, providing solid technical and talent support for the formulation and revision of standards.

This round of updates comes at a critical stage in China’s efforts to build a manufacturing powerhouse and strengthen quality development. It also coincides with an important phase of the nonferrous metals industry’s pursuit of “carbon peaking and carbon neutrality” goals. The release and implementation of these new standards will promote technological progress and industrial upgrading in hydrometallurgy, improve resource efficiency, reduce energy consumption and environmental pollution, and play a significant role in advancing green, low-carbon development and enhancing the security and stability of the industrial supply chain.

Mr. Zhang Guoyi, Chairman of Daze, stated:
“Standards are the technical foundation and essential support for industry development. As a leading enterprise in the field, we are deeply aware of our great responsibility. Looking ahead, we will continue to leverage our technological strengths, work hand in hand with industry partners, further improve the standard system, and drive technological innovation. Our goal is to enhance the core competitiveness of China’s nonferrous metals industry and contribute to its high-quality development.”

Looking Ahead, Creating a Brighter Future Together

With the release and implementation of the new standards, Daze will take this update as an opportunity to further strengthen collaborative innovation with upstream and downstream enterprises in the industry chain, continuously drive technological progress and product upgrading, provide customers with higher-quality products and services, and inject new momentum into industry development.

Daze will always uphold its mission of “providing the highest-quality electrode materials and technical services for global hydrometallurgical enterprises,” and work together with industry peers to write an even more brilliant chapter for China’s nonferrous metals industry.
