process of salt mining Galaxy Resources, which mines spodumene mined in Australia, for example, first crushes and heats the ore in a rotary calcining kiln in order to convert the lithium crystal phase from alpha to beta (a process referred to as decrepitation). This allows the lithium present in the ore to be displaced by sodium.
