Delithiated Beta Spodumene (DBS)

Description

Spodumene is typically found in hard rock pegmatites and consists of lithium-aluminium-inosilicate. As a source of lithium, it can be processed to extract lithium carbonate or lithium hydroxide, compounds used to make valuable products such as lithium-ion batteries, ceramics, greases and lubricants. Australia is a leader in the supply of critical lithium battery minerals needed to power the battery electric vehicle revolution. The development of some of the largest and highest-grade spodumene resources in the world is well underway. With six existing lithium mines, and more to follow, Australia will remain a key global supplier of lithium minerals well into the future. Several lithium companies including Covalent Lithium and Tianqi Lithium are also pursuing local beneficiation opportunities in Australia by building chemical plants to convert spodumene concentrate into lithium hydroxide. This chemical conversion, which uses both pyro-metallurgical and hydro-metallurgical processes, also manufactures a lithium aluminosilicate product termed Delithiated Beta Spodumene (DBS) – a new and emerging class of manufactured pozzolan. Industry predictions based on forecast lithium demand growth, coupled with additional domestic lithium chemical processing, will result in significant quantities of DBS being supplied in Australia over the coming years.

Application and Uses

APozA is working with Standards Australia to develop AS3582.4 – Manufactured Pozzolans certifying DBS for use as a supplementary cementitious material in concrete, mortar and related applications.
