Scientists from the Russian State Corporation Rosatom have created a technology to process mica containing lithium, mined at the Nurlikon deposit in Uzbekistan, that produces no waste.
According to Rosatom's press service, this method allows for the extraction of 94.44% of the lithium into finished products, as well as the reuse of industrial waste in the production cycle.
The development belongs to specialists from JSC 'Giredmet', which is part of Rosatom's scientific division. The technology is designed for processing ore containing about 0.5% lithium oxide.
According to the developers, traditional enrichment methods cannot effectively separate the mineral from the surrounding rock due to the similarity of their properties. Furthermore, the high content of carbonates in the raw material creates additional complexities in the processing process.
One of the key aspects of the new technology is the use of phosphogypsum—an industrial byproduct of the Almalyk Chemical Plant—as raw material at an intermediate stage of processing. It is expected that this will allow for the annual use of about 225,000 tons of phosphogypsum.
The planned processing capacity is 750,000 tons of ore per year. JSC 'Giredmet' reports that this will ensure the production of over 8,500 tons of high-purity lithium carbonate grade KhCh.
The technology is designed to eliminate the formation of both liquid and solid waste. Washing tailings are planned to be used as raw material for the cement industry.
Valery Golovko, head of the technical department of JSC 'Giredmet', noted: 'We deliberately chose a zero-waste model. For low-grade mica ores, this is not just an environmental requirement but an economic necessity. Phosphogypsum, which is currently an industrial waste, is turned into a reagent, and washing tailings become raw material for the cement industry. As a result, we obtain high-purity lithium carbonate.'
Golovko also reported that pilot-industrial tests are planned for next year to prepare the technology for full-scale implementation.
