In step 1, to convert spodumene into lithium sulfate (Li 2 SO 4), the raw ore is crushed and separated both mechanically and via floatation.Next, the concentrate undergoes energy- and chemically intensive hot acid-roasting. This process (as shown in Figure 1 below) sees concentrated spodumene powder roasted at 1050°C, cooled, …

"Spodumene mineral is a source of lithium for lithium ion batteries. Thus, the production of a spodumene concentrate with an approximate grade of 6% Li2O is targeted. Traditionally, spodumene is concentrated by froth flotation using fatty acid as the collector. Amine collector can also be used to float mica ahead of spodumene as required or …

A typical run of mine spodumene ore assays about 1–2% Li 2 O, which is subjected to a series of processes to yield a beneficiated concentrate having a lithium content of about 6–7% Li 2 O. Table 2 shows the global spodumene-bearing pegmatite resources [25], which indicates that Australia tops the chart.

Spodumene ore naturally occurs in the crystal structure of monoclinic alpha form (α-form). In order to extract lithium from the ore via the leaching process, however, the ore's crystal structure must be in the tetragonal beta form (β-form). ¹ This conversion is achieved through decrepitation, or the shattering of the crystal structure.
