Lithium Still a Valued Source, Encouraging Old Mines to Re-Open

Pegmatites are igneous rocks that contain exceptionally large crystals and sometimes minerals, such as spodumene which is an ore of lithium. Traditional hard-rock mining of lithium-bearing pegmatite and spodumene is a costly and time-intensive endeavor, but the lithium concentrate is considerably higher, making these deposits competitive with ...

Mineralogy of Beryllium in Granitic Pegmatites | Semantic Scholar

Beryllium is one of the most widespread rare elements in granitic pegmatites. These rocks have been historically the sole industrial source of this metal (e.g., Norton et al. 1958), and they still contribute a significant proportion of the global output of beryllium ores. Hand-cobbed beryl constitutes a substantial proportion of beryllium ore concentrates in Africa, Asia and South America ...

GY313 GEOLOGY OF ZAMBIA.doc - UNIT 3: GEOLOGY OF ZAMBIA - Course Hero

The most common supergene minerals are malachite, cuprite, chrysocolla, chalcocite, vermiculite, tenorite and native copper. Copper sulphides occur as discrete irregular-shaped grains moulded onto and replacing the rock-forming minerals. The size of the sulphide grains are directly related to the size of the constituents of the host rock.

Lepidolite and spodumene are other common minerals which contain lithium. Commercial quantities of these three minerals are in a special igneous rock deposit that geologists call pegmatite. In pegmatites, magma cools so slowly that crystals have time to grow very large. Because lepidolite is a type of mica, its crystals grow into long thin sheets.
