Huaxia Jianlong's Jindi Mining Achieves a New Milestone in Comprehensive Utilization of Molybdenum Tailings Resources
In order to implement Chairman Yuan Zhanyong's directive of "transforming leading comprehensive resource utilization technology into one of the company's three core competitive strengths," various subsidiaries have been actively engaged in tackling technical challenges related to resource utilization, creating an increasingly vibrant research atmosphere and giving rise to numerous "Yang Shuafeng-style" scientific research achievements and personalities. Recently, Jindi Mining, a subsidiary of Huaxia Jianlong, has reported success in overcoming technical obstacles in its molybdenum tailings comprehensive utilization project, achieving a breakthrough in efficiently extracting mica concentrate from molybdenum tailings and recovering rare light metals such as lithium, rubidium, and cesium. Currently, all technical indicators are slightly higher than those of well-known universities and research institutes.
Molybdenum tailings are complex in composition, primarily consisting of quartz (41.21%), plagioclase (23.78%), potassium feldspar (17.19%), white mica (10.50%), and black mica (4.35%). The minerals have similar specific gravity, physical and chemical properties, and floatability, making beneficiation challenging. Additionally, lithium, rubidium, and cesium are almost entirely found in white mica. To achieve comprehensive utilization of these resources, the project team focused on mica extraction. After countless experiments and optimizations, they successfully separated mica concentrate with a yield rate of 5% from the molybdenum tailings, containing 0.12% rubidium, 170g/t cesium, 7.262% potassium, and 84g/t gallium, laying a solid foundation for industrial trials and efficient recovery of valuable elements.
Since 2024, under the guidance of the "Three Exemplary Figures" learning campaign organized by Huaxia Jianlong, Jindi Mining took the comprehensive utilization of molybdenum tailings as a breakthrough point. A project team was formed with Li Dongfeng, Liu Bin, Sun Jianxi, Zhang Zuojin, Li Pengfei, and Tan Rui as core members. They worked together to overcome difficulties and achieve key breakthroughs, leading a new trend in efficient utilization and technological innovation of molybdenum tailings resources. Next, the project team plans to further explore technologies for enriching valuable metals such as gold, copper, and cobalt from the sulfur powder in tailings and to delve into combining mica beneficiation technology with advanced pyrometallurgical and hydrometallurgical methods. The aim is to maximize the extraction of high-value components from mica, providing mature and reliable technical support for the comprehensive utilization and large-scale development of Jindi Mining's tailings resources.
