Technical strength


Relying on technological innovation to build sustained competitive capabilities, JinAo has established a robust technology innovation system that is enterprise-centered, market-oriented, and integrates industry, academia, and research. The company has created a multi-system, all-round innovation platform encompassing platforms for technological research, testing and experimental applications, industry-academia-research collaboration, as well as platforms for attracting and cultivating high-end talent. The company boasts a strong research team comprising more than 70 full-time R&D personnel holding various mid- and senior-level professional titles, along with over 10 externally hired experts. As a national high-tech enterprise, JinAo has built an independent R&D center and a pilot-scale testing base. It also holds several R&D platforms, including the Shandong Provincial Enterprise Technology Center, the Yantai Municipal Enterprise Technology Center, the Yantai Municipal Industrial Enterprise “One Enterprise, One Technology” R&D Center, and the Yantai Industrial Design Center. Since its inception, JinAo has obtained certification for and continuously operates under the ISO9001 quality management system, the ISO14001 environmental management system, and the ISO45001 occupational health and safety management system.

The company places great importance on intellectual property work. Through continuous R&D, the company has mastered advanced technologies—including the “exploration, mining, beneficiation, smelting, and environmental protection” integrated system—under its own intellectual property rights. To date, the company has been granted more than 50 authorized patents. Moreover, its innovation “A Method for Recovering Gold and Silver from High-Arsenic Gold Concentrates” has received the “China Science and Technology Innovation Invention Award” presented by the China Institute of Management Science. The technical and process standards of the company have reached the advanced level of the industry.

In the future, the company will continue to uphold its research and development philosophy of “driving sustained growth through technological innovation,” adhering to a market-oriented approach and focusing on efficiency. By continuously improving management in areas such as technology R&D and intellectual property, the company aims to enhance its competitive position in the market, promote technological innovation within the enterprise, and strengthen its core competitiveness.

Innovative Collaboration


While continuously strengthening its own capabilities in scientific and technological innovation, JinAo is fostering an open innovation ecosystem by engaging in industry collaborations, participating in government projects, and deepening the integration of “industry, academia, and research” with universities and academic research institutions both at home and abroad. This collaborative approach is designed to jointly promote research on new technologies and the development of new products. JinAo has established cooperative platforms such as the Technical Center Workstation for Senior Experts of the Chinese Academy of Sciences and the Industry-Academia-Research Base of the Lanzhou Institute of Chemistry and Physics, Chinese Academy of Sciences. In the future, JinAo will further encourage enterprises to set up joint laboratories with universities and research institutes, jointly conduct research projects and cultivate talent, and accelerate the commercialization of existing scientific and technological achievements—key initiatives that will support the upgrading of the company’s technological R&D capabilities.
