At 10:00 a.m. on May 31, Guizhou Sanxiang Technology Co., Ltd. (referred to as Sanxiang Company) held the groundbreaking ceremony for its annual project aimed at resourcefully recycling and comprehensively utilizing 1 million tons of electrolytic manganese slag in Songtao County, Guizhou Province. This marks another solid step forward in Songtao County’s efforts to tackle manganese pollution, serving as a milestone that will significantly advance the harmless treatment and resource recovery of manganese slag across the entire manganese industry. [Image: Scene from the groundbreaking ceremony of Sanxiang Company’s electrolytic manganese slag recycling project] The Songtao County Party Committee and County Government have prioritized the management of manganese pollution and the high-quality development of the manganese industry as their "top political priority." In response, manganese-related enterprises in Songtao County have taken proactive measures, actively assuming responsibility for pollution control. At the end of 2022, Songtao Sanhe Manganese Industry Group Co., Ltd. joined forces with Hunan Jianxiang High-Tech New Technology Company to establish Sanxiang Company, which is now constructing and implementing this landmark project—processing 1 million tons of electrolytic manganese slag annually through resourceful recycling and comprehensive utilization—in Songtao County. This initiative represents a pioneering effort in achieving low-cost, harmless, and sustainable treatment and resource recovery of manganese slag in the region. The project is planned to require a total investment of 180 million yuan, with a designated site area of 73.191 mu. Chen Jianxiang, General Manager of Sanxiang Company, stated: "Once operational, the project will be capable of processing 1 million tons of electrolytic manganese slag each year, producing 600,000 tons of cement-based building materials suitable for use as cementitious materials. Based on a price of 45 yuan per ton, this process will effectively eliminate 1 million tons of waste annually, generating an annual revenue stream of 27 million yuan from these valuable cementitious products." The project employs a two-stage calcination technology designed specifically to treat electrolytic manganese slag. It combines low-temperature drying and deamination with high-temperature activation and sulfur fixation through calcination, optimizing the processes of ammonia removal at low temperatures and sulfur stabilization along with heavy metal immobilization during high-temperature treatment. This approach maximizes the extraction of ammonia nitrogen from the slag, fixes sulfur compounds, and stabilizes harmful heavy metals, ultimately enabling the production of high-quality cementitious materials essential for the construction industry. With the official launch of this project, Songtao County will now fill the critical gap in large-scale applications for the harmless treatment and resourceful utilization of manganese slag—a breakthrough that not only facilitates the effective commercialization of cutting-edge scientific and technological advancements but also addresses key challenges in the high-quality development of the manganese industry. This initiative ushers in a new chapter for the resourceful use of manganese slag, paving the way for Songtao County—and even the broader "Manganese Triangle"—to achieve a lasting solution to manganese pollution. Moreover, the project holds groundbreaking significance for the global community, setting a precedent for the innovative and sustainable treatment and recycling of manganese slag worldwide.
5 At 10 a.m. on the 31st, Guizhou Sanxiang Technology Co., Ltd. (referred to as Sanxiang Company) held the groundbreaking ceremony for its annual project aimed at the resourceful and comprehensive utilization of 1 million tons of electrolytic manganese slag in Songtao County, Guizhou Province. This marks another solid step forward in manganese pollution control for Songtao County and represents a milestone in advancing the harmless treatment and resource recovery of manganese slag across the entire manganese industry.

The Songtao County Party Committee and County Government are treating the advancement of manganese pollution control and the high-quality development of the manganese industry as their "top political priority." Meanwhile, manganese-related enterprises in Songtao County have taken proactive steps, actively assuming responsibility for pollution management. At the end of 2022, Songtao Sanhe Manganese Industry Group Co., Ltd. partnered with Hunan Jianxiang High-Tech New Technology Company to establish Sanxiang Company, which is building and implementing a landmark project in Songtao County: a year-round, 1-million-ton capacity facility dedicated to the resource-based, comprehensive utilization of electrolytic manganese slag. This initiative marks a significant breakthrough in achieving low-cost, harmless, and sustainable treatment and recycling of manganese slag in Songtao County.
The project is planned to have a total investment of 180 million yuan, with the project’s red-line area covering 73.191 mu of land. Chen Jianxiang, General Manager of Sanxiang Company, stated: "Once operational, the project will be able to process 1 million tons of electrolytic manganese slag annually, producing 600,000 tons of cement and building material-grade cementitious materials. If calculated at 45 yuan per ton, this will enable the annual elimination of 1 million tons of waste residue, generating 27 million yuan in revenue from the sale of these cementitious materials."

The project utilizes electrolytic manganese slag and other primary materials, employing a two-stage calcination process: low-temperature drying followed by deammoniation, combined with high-temperature activation and calcination for sulfur fixation. This innovative approach optimizes the processes of low-temperature deammoniation of manganese slag, high-temperature sulfur solidification, and heavy-metal stabilization, effectively removing ammonia nitrogen from the slag while immobilizing sulfur and stabilizing harmful metals. The treated material is then further processed into a cementitious binder essential for constructing building materials like concrete.
With the launch of this project, it will fill the gap in large-scale, harmless treatment and resource utilization of manganese slag in Songtao County, truly enabling the effective commercialization of scientific and technological advancements. This breakthrough addresses a critical bottleneck in the high-quality development of the manganese industry, marking the beginning of a new chapter in the resourceful use of manganese slag—and paving the way for a comprehensive solution to manganese pollution not only in Songtao County but across the entire "Manganese Triangle." Moreover, this initiative holds groundbreaking significance for the nationwide, and even global, efforts toward the harmless treatment and sustainable utilization of manganese slag.
