Battery-grade Lithium Hydroxide Produced in a Test Programme Based on Ore from Keliber’s Largest Deposit
Keliber has completed a four-phase pilot-scale test programme and verified the behaviour of the ore from the company's largest deposit, Rapasaari, at all stages of the production process. A similar pilot-scale test programme has previously been carried out using ore from Syväjärvi, the mine where quarrying will start first. In the last phase of the test programme, battery-grade lithium hydroxide monohydrate was produced from spodumene concentrate that had been treated in a high-temperature conversion in a rotary kiln.
