Uzbekistan is plotting a tighter grip on critical minerals by seeking to purchase tungsten concentrate from Kazakhstan, as Uzbekistan’s government-led Uzbek Metal Processing Plant (TMK) prepares to ramp up production. Metin Alemder, TMK’s technical adviser, told inbusiness.kz at the China Mining summit in Tianjin that TMK is in talks with Kazakh colleagues to secure tungsten concentrate, signaling a strategic push to source raw materials locally for its expanding operations.
Kazakhstan has been developing tungsten at the Boguty mine in the Almaty region near the Charyn Canyon. The project is led by Zhetyсу Wolfram LLC, in which Chinese-backed Jiaxin International Resources Investment Limited is a major shareholder. Boguty is regarded as one of the world’s larger tungsten deposits, with a mining licence valid through 2040. Early projections estimated an annual processing capacity of 3.3 million tonnes of ore to produce about 10,000 tonnes of 65% tungsten oxide concentrate, primarily destined for China. The site also contains molybdenum, bismuth, and beryllium, with plans to raise tungsten extraction to nearly 5 million tonnes of ore by 2027.
Other Kazakh tungsten prospects include Aksoran at the SCO-Akmola border, as well as Northern Katpar and Verkhnee Kairakty in Karaganda. Notably, the last two are set to be developed via a joint venture in which Cove Capital (70%) partners with state mining firm Tau-Ken Samruk (30%) in a project budget of about $1.1 billion, with production expected to start in roughly 3.5 years. Cove Capital also has interests in Uzbekistan.
Alemder notes that China already controls more than 80% of global tungsten production and leads fundamental research in this strategic metal, which Czech-like knowledge in Uzbekistan could help leverage. Tungsten is not a rare earth metal, but it remains a critical material due to its unique properties and supply concentration.
TMK currently relies largely on local tungsten concentrates, with Uzbekistan able to produce tungsten using both hydrometallurgical and pyrometallurgical methods. The company’s plant in Chirchik is expanding capabilities, and a new hydrometallurgical workshop in Samarkand is slated to begin in 2027, targeting 5,000 tonnes of tungsten oxide annually. By 2030, production is expected to reach 15,000 tonnes per year, requiring growing external ore supplies. In the interim, the plant utilises residual tailings from an older deposit.
In addition to tungsten, TMK is expanding molybdenum production from tailings from the Almalyk Mining and Metallurgical Complex and is developing tellurium and osmium. A sulfuric acid plant with a capacity of 500,000 tonnes annually is under construction, feeding consumables for the chemical sector, fertiliser production, and uranium mining via in-situ leaching, using sulfur supplied by Uzbekneftegaz and local gas-processing facilities.
