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.

Limestone is most commonly employed as rough block for building and construction. Additionally, it is used as dressed stone in various applications including curbing, paneling, veneer, and tile. Two general phases of limestone production exist: quarrying and processing. Each of these phases is described below.
6.1.1 Extracting Metals
Limestone (calcium carbonate) is added to the furnace to remove impurities in the ore. The calcium carbonate in the limestone decomposes to form calcium oxide: CaCO 3 (s) → CaO (s) + CO 2 (g) The calcium oxide formed reacts with the silicon dioxide, which is an impurity in the iron ore, to form calcium silicate
