Process whereby rocks and minerals are dissolved in solution, like salt in water. Quantitatively, the most important minerals involved in dissolution are the carbonate minerals, calcite and dolomite. Some rock types can be completely dissolved. Rock salt is perhaps the best known example. Gypsum is less soluble than rock salt but also easily dissolved by surface water.

INTRODUCTION Lithium is found in very low concentration in igneous rocks. The largest concentrations of lithium-containing minerals are found in granitic pegmatites. The most important of these minerals are spodumene (Li 2 O, Al 2 O 3. 4SiO 2) and petalite (Li 2 O, Al 2 O 3. 8SiO 2). Spodumene has a theoretical Li2O content of %. Due to its
