Characterization of Pegmatoid from Dimension Stones Tailings for Application as Ceramic Raw Material
2014
Journal of Chemistry and Chemical Engineering
Exploitation and processing of pegmatoids at Brazil's northeast (Serido region-RN State) aiming further use as dimension stone produces mass losses ranging between 30%-90%. The tailings are predominantly composed by feldspar, quartz, muscovite and other Fe-bearing silicates such as biotite and amphiboles, suitable for ceramic production. The recovery of these elements depends on mica's remotion to levels under 2.0%, preferentially by dry methods due the scarce amount of water prevailing at
