Mineral Processing - an overview ScienceDirect Topics

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Hard Rock Lithium Processing - SGS

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 8.03%. Due to its high lithium ...
