On April 8, 2023, the comprehensive recycling of polymetallic resources and environmental protection upgrading and transformation project of Western Henan Mining was fully started, marking that Western Mining has taken a new and solid step in promoting the development of a higher level of green and low carbon cycle.

It is reported that the comprehensive recycling of polymetallic resources and environmental upgrading and transformation project in Western Henan is a key project of the 14th Five Year Plan of Qinghai Province, an important project for Western Mining to unswervingly follow the green and low-carbon carbon cycle development path, and promote the green transformation and upgrading of the industry. It is also a key project for the company to form an integrated smelting system of copper, zinc and lead, promote the construction of a regional dual cycle economic system, and achieve the goal of getting rid of resources.

In recent years, Western Mining has firmly grasped the three largest provincial positioning, closely focused on the theme of high-quality development, established a comprehensive, long-term, and holistic view, adhered to integrating green development into the entire process of enterprise reform and development, highlighted the deep integration of green development and enterprise reform, promoted the coordinated development of resource development and utilization and ecological environment protection, injected strong momentum into promoting high-quality development of enterprises, and successfully walked out of the integration of development and ecology A new green development path that benefits both ecology and economy.

The Comprehensive Recycling and Environmental Protection Upgrading and Renovation Project of Multi metal Resources in Western Henan revolves around the four high requirements of high environmental protection level, high automation level, high labor productivity, and high resource utilization level in western mining. Based on comprehensive digitization and intelligence, it fundamentally changes the existing production organization mode in Western Henan, forming cross unit horizontal control from five dimensions of equipment, power, production, quality, and safety, Realize professional management so as to improve the all-round collaboration ability, vertically integrate the three main process flows of pyrometallurgy, acid making and electrolysis, break the overall framework of five horizontal and three vertical barriers between materials, data and personnel, and finally realize the definition, collection, processing, storage, analysis and external services of comprehensive data through the Industrial Internet platform; Realize the digitization of assets such as personnel, equipment, materials, and media, as well as the digitization of production processes; Realize centralized and intelligent control throughout the entire process of the factory. By significantly improving the working environment on the production site and reducing labor intensity, it can also improve production efficiency and reduce production costs.

The project plans to invest 2.099 billion yuan and adopt internationally leading processes, using gold concentrate, silver concentrate, low-grade polymetallic ore, and the tailings produced by the company's copper and zinc smelting as the main raw materials. By combining with lead concentrate and using lead as the carrier, various valuable precious metals will be comprehensively recovered, forming an annual production capacity of 200000 tons of lead, 6 tons of gold ingots, 430 tons of silver ingots, and 250000 tons of sulfuric acid. At the same time, copper, zinc, antimony, bismuth, selenium will be recovered Valuable metals such as palladium. After the completion of the project, it is expected to achieve an annual output value of up to ten billion yuan, with internationally advanced technology and superior energy efficiency compared to the domestic first-class level. This will effectively promote the construction of a regional dual circular economy system, ensure the maximum comprehensive utilization of regional resources, achieve green, circular, and low-carbon development, and provide a strong force for the economic and social development of Golmud, Haixi Prefecture, and even Qinghai Province, Make state-owned enterprise contributions to the construction of six modern new Qinghai provinces.
