Overview

Quartz is silica occurring alone in pure state. It is the second most abundant mineral in the Earth's crust, after feldspar. It is made up of a continuous framework of SiO₄, with each oxygen being shared between two tetrahedra, giving an overall formula SiO₂. There are many different varieties of quartz, several of which are semi-precious gemstones.

Uses & Applications

Glass Making
as an Abrasive
Foundry Sand
Petroleum Industry in hydraulic fracturing
Quartz sand is used as a filler in the manufacture of rubber, paint and putty.
Quartz sands are used for traction in the railroad and mining industries.
Electronics grade crystals can be used in filters, frequency controls, timers, electronic circuits that become important components in cell phones, watches, clocks, games, television receivers, computers, navigational instruments and other product
Optical-grade crystals can be used as lenses and windows in lasers and other specialized devices.

Occurrence

Commercially exploitable quartz rock crystal occur in pegmatites and quartzites hosted by rock of the basement complex around Egbe, Udiarehu, Okene and Lokoja in Kogi State, Ijero in Ekiti State. The quartzites occur in the medium to high grade metamorphic terrains of the basement complex. The vein quartz and quartz bearing pegmatite solidified from the hydrothermal fluids associated with the older granites as well as those of the Younger Granites and from the materials of the rocks of the basement complex at different periods.

Investment Opportunities

Nigeria is richly endowed with a variety of solid minerals including quartz. However the level of exploitation of these minerals is very low in relation to the extent of deposits found in the country. Quartz deposits are available in many states in Nigeria awaiting exploitation and processing to meet local and export demands. In order to encourage investment in the sector, the Federal Government has formulated the new National Policy on Solid Minerals is to ensure the orderly development of the mineral resources of the country.
