Development Potential of Green Gold Metallurgy in China
Gold is a scarce type of global strategic resources. The gold industry needs to follow the trend of green, low-carbon, and intelligent development, and promote its high-quality development through green metallurgy. The development of green metallurgical technologies and the innovation in cyanide tailing treatment technologies are closely related and complementary, together constituting the core content for the green transformation of the gold industry. From the perspectives of resource constraints, environmental challenges, and scientific and technological application, this study analyzes the demand and industry overview of China's gold industry, sorts out the research and application progress of green technologies regarding gold metallurgy from both international and domestic perspectives, and further discusses the current status and technical application of cyanide tailing treatment in the gold industry. Considering the current status of the gold industry, the study identifies the development potentials of green gold metallurgy. Specifically, non-ferrous-associated gold smelting and secondary resource recycling are two important directions to break the limitations of traditional gold resources; high-end new materials are key for industrial upgrading under the manifestation of gold's scientific and technological attributes; intelligent transformation is a strategic path for the production mode innovation and efficiency improvement of the gold industry; and industrial integration and clustering is the preferred solution for ecological reconstruction and collaborative innovation of the industry. Furthermore, it is recommended to enhance the safe utilization and ecological consumption of gold cyanide tailings, strengthen the development of gold's scientific and technological attributes and high-end utilization, and promote the integrated development of non-ferrous metals and the gold industry, thereby ensuring the sustainable development of China's gold industry.
