en.Wedoany.com Reported - At 16:16 on June 11, 2026, Xinjiang Nonferrous Metal Industry Group Yili Co., Ltd. (referred to as "Yili Company") held the ignition ceremony for the technical renovation project of comprehensive development and utilization of complex gold concentrate at its smelter located in Zone A of Yidong Industrial Park, Yining County, Yili Kazak Autonomous Prefecture, Xinjiang. As the ignition button was pressed, flames ignited in the smelting furnace, marking the official entry of the project into the trial production phase. All cadres and staff of Yili Company's smelter, along with representatives from project partners Jinchuan Group Machinery Manufacturing Co., Ltd. and Quanxin Construction Co., Ltd., witnessed this moment together.

Yili Company is a subsidiary of Xinjiang Nonferrous Metal Industry (Group) Co., Ltd. (referred to as "Xinjiang Nonferrous Group"). Xinjiang Nonferrous Group is a first-class state-owned enterprise under the supervision of the State-owned Assets Supervision and Administration Commission of Xinjiang Uygur Autonomous Region. Its predecessor can be traced back to "Sino-Soviet Nonferrous and Rare Metals Joint Stock Company," one of the first Sino-foreign joint ventures established in 1950 in New China. It has now developed into a large enterprise group focusing on the development of nonferrous and precious metals, rare metals, and ferrous metal resources, integrating geological exploration, mining, beneficiation, smelting, scientific research, design, construction, and installation. Yili Company, formerly known as Xinjiang Axi Gold Mine, is a modern gold production enterprise integrating mining, beneficiation, and smelting.

This technical renovation project is a quality improvement and efficiency enhancement project based on Yili Company's actual conditions to overcome process bottlenecks. According to public information from the Department of Ecology and Environment of Xinjiang Uygur Autonomous Region, the project is classified as a technical renovation. It plans to modify the existing roasting and primary dust collection system, acid production system, etc., at the smelter, and construct a supporting tailings flotation system. The main engineering work involves building a new 35-square-meter fluidized bed roaster with a dry feed system and dust collection system in the existing roasting workshop, while decommissioning the existing two-stage fluidized bed roaster and its associated slurry preparation and feed system. The project is designed with a processing capacity of 220 tons per day, producing gold ingots and silver ingots as main products, and sulfuric acid as a by-product. The total investment is 40 million yuan, including 2.39 million yuan for environmental protection.

During the project construction, Yili Company actively coordinated various tasks including construction progress, quality control, safety production, and environmental management. The construction team, together with the contractor, overcame key difficulties such as technical renovation construction, system linkage, and technical adaptation one by one, completing preliminary work including engineering construction, equipment installation and commissioning, personnel training, as well as safety, environmental protection, fire-fighting facilities, process pipelines, and supporting utilities to high standards. After the renovation, the production process for complex gold concentrate will significantly improve the quality of industrial sulfuric acid and greatly increase production capacity. During the trial operation period, Yili Company will implement 24-hour monitoring, continuously tracking equipment operation status, process parameter fluctuations, production energy consumption indicators, and product quality, promptly optimizing production processes to ensure stable, efficient, and safe operation, and achieving project production targets as soon as possible.

This ignition for trial production marks the official transition of the technical renovation project from the construction phase to the production commissioning phase, which will help enhance Yili Company's capacity to process complex gold concentrate and improve the level of comprehensive resource utilization.
