Zunyi Tianci Manganese Industry Group and Zunyi Energy & Mineral Resources Group Visited the Institute of Chemical Engineering for Work Exchange.

        On March 11, Shi Yue, Chairman of Zunyi Tianci Manganese Industry Group, Yu Yang, Chairman of Guizhou Ronghui Energy & Mineral Development Co., Ltd. under Zunyi Energy & Mineral Group, and their delegation paid a visit to the Institute of Chemical Engineering for work exchanges. Lin Zhiyong, Secretary of the Party Committee and General Manager of the Institute of Chemical Engineering, Yang Fangwen, Deputy General Manager, and relevant heads attended the meeting.

Lin Zhiyong, on behalf of the Institute of Chemical Engineering, extended a warm welcome to the delegation from Tianci Manganese Industry Group and Zunyi Energy & Mineral Resources Group, briefly outlining the Institute’s development journey, business scope, technological innovations, strategic layout of manganese-based materials, and its strong technical capabilities. Deputy Chief Engineer Chen Min provided a detailed introduction to the full industrial chain of manganese-based materials and the technical team specializing in new energy battery materials, showcasing the Institute’s robust technical expertise across the entire manganese-based materials value chain. He expressed his hope that the Institute will work together with Tianci Manganese Industry Group and Zunyi Energy & Mineral Resources Group for mutual development in the future.

Shi Yue expressed his gratitude for the Chemical Research Institute’s warm hospitality and professional insights, and provided an overview of Tianci Manganese Industry’s development journey and technological strengths. He hoped that the Chemical Research Institute would offer relevant technical support to advance the Group’s industrial development. Yu Yang noted that Zunyi is rich in manganese, aluminum, and titanium resources, and that Zunyi Energy & Mineral Group— as a state‑owned enterprise under the Zunyi municipal government—is leveraging local resources to vigorously support the growth of private enterprises. He looked forward to establishing a long‑term, stable cooperative relationship with the Chemical Research Institute, using the Energy & Mineral Group as a platform to jointly promote the development of a more scientifically sound resource industry chain for manganese, aluminum, titanium, and other materials, and working together to empower Zunyi’s related enterprises.

This conference has laid the foundation for trilateral cooperation, leveraging each party’s core strengths to deeply integrate resources and technological capabilities, thereby jointly contributing to Zunyi’s green, low‑carbon transformation and high‑quality development.

At present, new energy battery materials are experiencing rapid development. High‑purity manganese sulfate, as a crucial raw material for ternary lithium batteries, is primarily used in the production of lithium manganate, manganese tetroxide, and nickel–cobalt–manganese ternary materials. With the advancement of lithium‑ion battery technology and the growing adoption of new energy vehicles, the market prospects for high‑purity manganese sulfate are particularly promising. The Chemical Research Institute has continuously delivered high‑quality manganese sulfate and high‑purity manganese sulfate projects that have been successfully designed, completed, and put into operation, while consistently leading the nation in process technology within the specialized fields of manganese sulfate and high‑purity manganese sulfate, and continually upgrading its engineering designs. The Guizhou Dalong Huicheng Battery New Materials Project integrates the production process for active manganese used in batteries with the production process for manganese sulfate used in batteries. After going into operation, it has achieved a global and domestic market share of over 60% for high‑purity manganese sulfate used in batteries for two consecutive years. The Guangxi Esokai 150,000 t/a high‑purity manganese sulfate project was ranked third among the “Most Capable to Build” Top 10 by China Energy Engineering Group in 2021 (it had previously won the Guangxi Steel Structure Gold Award in 2020). The 35,000‑ton‑per‑year technical renovation project for the comprehensive utilization of low‑grade, refractory oxidized manganese–silver ore and tailings at Eren Taolege in Jinshan Mining, Inner Mongolia, has been completed, successfully overcoming the technical challenges and bottlenecks in manganese–silver separation. After 2022, the Chemical Research Institute has continuously secured a series of contracts for manganese-based new energy materials, including: the first phase of Ningxia Tianyuan Manganese Industry’s 300,000-ton-per-year high‑purity manganese sulfate project—the world’s largest manganese enterprise; the 60,000-ton-per-year high‑purity manganese sulfate project for Hubei Changchen Lithium Energy; the high‑purity manganese sulfate and trioxide manganese project for Hunan Huoniao New Materials Co.; the energy‑saving and emission‑reduction upgrade and renovation project for the 300,000‑ton-per-year electrolytic metallic manganese production system at Ningxia Tianyuan Manganese Industry; the engineering design for the first phase of the manganese‑based new energy materials production project of Fujian Dexiang New Materials Co., Ltd. (including high‑purity manganese sulfate, trioxide manganese, and sulfuric acid); as well as feasibility studies and planning designs for a number of high‑purity manganese sulfate and trioxide manganese projects, such as those undertaken by Xinjiang Nonferrous Group Kebang Manganese Industry. In addition, on-site diagnostics were conducted to address the technical bottlenecks and cost‑reduction and efficiency‑improvement challenges encountered in the first phase, first step—30,000 t/a—high‑purity manganese sulfate production line of Guizhou Nengkeng Manganese Industry Group, resulting in the compilation of a “Specialized Diagnostic Analysis Report” for the high‑purity manganese sulfate production line.
