Core Viewpoint - The Karachal Fluorspar Mine, designed by China ENFI Engineering Corporation, has commenced production, marking it as the largest primary fluorspar mining and selection base in China and Asia, with a resource endowment that accounts for approximately 15% of the country's proven fluorspar reserves [1][2]. Group 1: Project Overview - The Karachal Fluorspar Mine has a production capacity of 1.2 million tons per year and is recognized for its superior resource endowment [1]. - The mine has achieved significant breakthroughs in the efficient selection of fluorspar from difficult-to-process calcite-type ores, overcoming major technical challenges such as the suppression of calcite, low-temperature selection, and coarse particle flotation [1]. - The project has designed a fluorspar recovery rate of over 80% and a fluorspar concentrate grade of 97%, establishing an engineering technology system for the efficient selection of calcite-type fluorspar [1]. Group 2: Technological Innovations - The Karachal Fluorspar Mine is the first non-coal underground mine in China to fully adopt non-explosive mechanical continuous mining technology during the design phase [2]. - This new mining process allows for parallel continuous operations in underground recovery, which is expected to significantly enhance mining efficiency, labor productivity, and safety management levels [2]. Group 3: Environmental and Energy Efficiency - The tailings dam of the project employs an upstream construction method and has been designed to adapt to cold climate conditions [1]. - A solar heat collection and storage system has been established to provide hot water for heating and slurry warming, thereby reducing electricity load and achieving significant energy savings [1].
