The Rare Metals and Hard Alloys Plant, part of the Uzbekistan Technological Metals Complex (TMK), has introduced a state-of-the-art, environmentally safe molybdenum processing technology — the first of its kind in Central Asia.
What is this technology?
Previously, the production of molybdenum products using ammonia water and acids resulted in the release of ammonia vapors into the atmosphere, posing environmental risks. Following the implementation of a new method, plant specialists developed a process based on a three-stage soda leaching system. Now, molybdenum raw materials are leached using a soda solution, and the entire process is carried out within a closed-loop system.
What are the advantages?
Ammonia water consumption reduced 4.4 times. Compared to the previous method, the new technology significantly lowers the use of ammonia water, promoting more efficient resource use and cost reduction.
Ammonia emissions fully eliminated. The closed-loop system prevents any release of ammonia vapors into the atmosphere — a major milestone in mitigating environmental risks.
Waste reduced fourfold. In the first half of 2022, harmful emissions into the atmosphere totaled 0.9 tons — well below the allowable limit of 3.9 tons — reflecting a fourfold reduction.
Safe and eco-friendly production environment. The closed technological cycle not only minimizes waste, but also ensures a safer working environment for plant personnel.
95% air purification efficiency. The hydrometallurgical workshop is integrated into a unified aspiration system that captures up to 95% of airborne pollutants.
Through this innovation, TMK has enhanced its production efficiency while setting a regional benchmark in environmental sustainability and resource efficiency. This achievement stands as an important example at both the national and regional levels.
