Central Asia Molybdenum Mine Project

Project Background

The average grade of the mine is 0.3%, with a potential economic value of over 500 billion yuan. However, the local mineral processing technology is outdated, and the comprehensive utilization rate of resources is less than 40%, and modern technology is urgently needed to improve efficiency. With its core technical advantages in the field of molybdenum ore beneficiation and global project experience, ZOOMJO GROUP successfully undertook the construction of the molybdenum ore beneficiation plant. The project adopts intelligent and low-energy design to help the country achieve efficient development and sustainable utilization of molybdenum ore resources.

Production line process

Molybdenum ore crushing
After blasting, the raw ore enters the heavy-duty vibrating feeder through the silo and is evenly transported to the jaw crusher for coarse crushing (primary crushing, particle size ≤100mm), followed by a multi-cylinder hydraulic cone crusher for medium and fine crushing (secondary crushing, particle size ≤25mm), providing ideal raw materials for subsequent grinding.

Molybdenum ore grinding
The crushed molybdenum ore particles enter the energy-saving ball mill for closed-circuit wet grinding, and are matched with a double spiral classifier to achieve particle size classification control. Substandard particles (>0.2mm) are returned to the ball mill for cyclic grinding, and qualified ore pulp (fineness -200 mesh ≥90%) enters the flotation system.

Molybdenum ore flotation
The ore pulp is fully mixed with collectors, frothers and other reagents in the high-efficiency pre-processor, and then enters the aerated mechanical stirring flotation machine for "one roughing, two sweeping and three fine" multi-stage flotation, and finally obtains a concentrate pulp with a molybdenum grade of ≥45%. The tailings are discharged in compliance with the standards after environmental protection treatment.

Dehydration of concentrate
The molybdenum concentrate slurry after flotation is efficiently concentrated by a deep cone concentrator, the bottom flow is initially dehydrated by a vertical filter press, and then deeply dried by a gas-fired rotary dryer, and finally the finished molybdenum concentrate powder (Mo≥50%) with a moisture content of ≤8% is produced, meeting international smelting standards.

Project Achievements

After the production line was put into operation, the recovery rate of molybdenum concentrate increased from 65% of the traditional process to 92%, the concentrate grade was stabilized at more than 50%, the annual processing capacity exceeded 300,000 tons, and the comprehensive energy consumption was reduced by 25%. The intelligent control system independently developed by ZOOMJO GROUP realizes full-process automated management, reduces manual intervention by 40%, and significantly reduces operating costs. The project not only drives the upgrading of local mining technology, but also creates more than 300 jobs, becoming a benchmark project for molybdenum mine development in Central Asia. Through this project, ZOOMJO GROUP has further consolidated its technological leadership in the field of global molybdenum ore dressing, and provided a successful model for the "Belt and Road" mineral resources cooperation.
