The beneficiation of lithium minerals from hard rock ores: …

 · Pegmatite deposits are currently the main sources of lithium from minerals owing to their relatively coarse grain-sized crystals making processing less complicated. However, extraction of lithium from mineral concentrates remains a costly and challenge due to the requirement for high temperature pre-treatment prior to intense leaching.

Pegmatite | SpringerLink

Pegmatites are holocrystalline usually leucocratic rocks that are, at least in part, exceptionally coarse-grained, and in which extreme variations in grain size are widespread. Their dominant constituents are minerals typically found in ordinary igneous rocks. Some pegmatites also contain less common minerals.

 · Diamond-bearing kimberlite pipes were discovered in northern Colorado and southern Wyoming in the 1970s, and the flurry of exploration that located some thirty-five pipes (depending on how one counts the individual pipes and dikes, which tend to occur in clusters) led to full-scale open-pit diamond mining at the Kelsey Lake mine from 1996 to 1998.


A hot spring is a spring that is produced by the emergence of geothermally heated groundwater from the Earth''s crust, and usually defined as spring water warmer than the human body (Figure 7-77).

Pegmatites occur in all parts of the world and are most abundant in rocks of relatively great geologic age. Some are segregations within much larger bodies of intrusive igneous rocks, others are distributed in the rocks that surround such bodies, and still others are not recognizably associated with igneous rocks.


Gener- ally, a fractured aggregate particle will be found at the bottom of the hole with the other part of the aggregate still adhering to the point of the popout cone. Most popouts are about 25 to 50 mm (1 to 2 in.) wide; however, popouts caused by sand particles are much smaller, and very large popouts may be up to 300 mm (1 ft) in diameter.
