ANZAPLAN verifies Keliber’s battery grade lithium hydroxide crystallization

Keliber Oy is a Finnish mining and chemical company with an aim of producing battery grade lithium hydroxide for the needs of the growing international lithium battery market. The deposits held by Keliber are Syväjärvi, Rapasaari, Länttä, Emmes, Outovesi and Leviäkangas, in Finland. Keliber’s JORC 2012 compliant measured and indicated mineral resources amount to 11.767 million tonnes, using a 0.50% Li₂O cut-off grade. Including the inferred mineral resources category, the mineral resources of the company amount to 14.194 million tonnes at an average Li₂O grade of 1.08%.

A continuous lithium hydroxide piloting conducted from Keliber's own ore served as a proof of concept for Keliber’s envisaged production process (Keliber’s press release, February 17, 2020). Keliber decided to use ANZAPLAN’s services as an independent third party to verify that Keliber’s lithium battery grade lithium hydroxide monohydrate (LiOH.H2O) meets battery grade specifications. In December 2020, ANZAPLAN successfully confirmed that the sample from the test program could be recrystallized to yield battery grade purity (Keliber’s press release, January 11, 2021).
