Sergio Ramos looked to have finally kick-started his career at Paris Saint-Germain when he made his debut against Saint-Etienne last Sunday, but this optimism has quickly disappear
Abundant Li-Cs-Ta aplite-pegmatite dykes were emplaced in the western Central Iberian Zone of the Iberian Massif during the Variscan Orogeny. Their origin and petrogenetic relationships with the widespread granitoids have led to a currently rekindled discussion about anatectic vs. granitic origin for the pegmatitic melts. To deal with these issues, the aplite-pegmatite dykes from the …
A spodumene rock was used as a flux in ceramic bodies, analyzing its reactivity to other raw materials such as quartz and kaolin. The petrology properties of the pegmatite (parent rock) from which the flux is extracted was characterized. The grindability, fluxing strength and pyroplastic deformation of the spodumene rock were investigated. The influence on technological …

Heating of β-spodumene (mineral and synthetic) and sodium carbonate was studied. • NaAlSi 2 O 6 is produced by Li + substitution in β-spodumene after heating at 400 °C.. At high temperature (above 600 °C) NaAlSiO 4 is obtained.. Li 2 CO 3 is recovered from a mixture containing NaAlSi 2 O 6 with a yield of 70%.. β-spodumene displays similar thermal behavior regardless its origin.

In the case of Länttä, spodumene is the main lithium mineral and a grade of 5.20 % Li 2 O is the maximum obtained in the concentrates, whilst lepidolite is the lithium-bearing mineral in Gonçalo and that can be concentrated by froth flotation up to 4.50 % Li 2 O. Taking into consideration the Li 2 O content of both Länttä spodumene and ...

Spodumene is worked as an ore of lithium, but it is most highly prized as a gem material - the varieties Kunzite (pink) and Hiddenite (green) are especially sought after. It is usually found as a constituent of lithium-rich pegmatites. It forms crystals to 12 meters in length.
