International buyers all over the world are always looking to purchase Dolomite from Nigeria because of its quality, abundance, and price. The large demand for this mineral in Nigeria by international buyers makes venturing into the export of Dolomite minerals from Nigeria to several countries around the world a lucrative export business to start up.
Dolomite or [CaMg(CO3)2] is a sedimentary rock abundantly found in Precambrian carbonate rocks with additional microbial structures attached to it. Talking about its physical appearance, pure dolomite resembles Micrite. It is produced when a preexisting carbonate rock is chemically altered. However, it is a rare site in the carbonate background these days.
Origin Of Dolomite:
The origin of dolomite is not accurately known to geologists around the world. Some believe it is a primary origin precipitated directly from sea water while some say it is a secondary origin which happens to be a product of post-depositional changes of calcitic carbonates.
However, it is interesting to know that dolomitic rocks were once found as limestone. Owing to this discovery, most scientists interpret that most dolomite rocks were formed through pressure solution. Well, what happens in pressure solution is that a carbonate rock dissolves under pressure as a result of deep burial or tectonic squeezing. If that was the case, many geologists believe that modern day limestone too is undergoing dolomitization, especially those in tidal flat environments.
Dolomite is one of the major constituents of dolostones and dolomite marbles. Whatsoever, the origin of dolomite-rich rocks in marine aspect is still an unresolved petrogenesis. Today, it is manufactured and exported in the market for different purposes.
Occurrence of dolomite in Nigeria
Dolomite is a solid mineral that occurs in several areas in Nigeria, mainly the Southwest and Middle belt regions of the country.
Its occurrences arise from the hydrothermal metasomatism or diagnosis of limestone in such places.
Also, the occurrences of dolomites deposits have been discovered in different areas in Nigeria, among them are Alagutan dolomite in Oyo state, Oreke dolomite in Ifelodun Local government area, Kwara State, Nigeria, etc.
Most Nigerians and West Africans may not be conversant with what dolomite actually is, and the word may really sound new to some persons when being compared to some of the minerals commonly found in the country.
It has many commercial and industrial uses, and because of this, there are many businessmen in Nigeria and numerous African countries that have invested in the mineral-dolomite, there are also a number of exporters and suppliers of this natural mineral resource across Nigeria too.
Physical Properties of Dolomite
Dolomite exhibits various physical properties such as vitreous, pearly soft glow, white streak mark, and diaphaneity ranging from transparent to translucent.
Colours of Dolomite:
It can be colorless, white, pink, green, gray, brown, or black in colour.
Type of Dolomite Rock:
The most common type of dolomite rock that is widely known is the former limestone before its dolomitization.
Dolomitization of limestone means that its main constituent, calcite or aragonite calcium carbonate was substituted with mineral dolomite, magnesium ions.
It's a geological process through the action of magnesium-bearing water percolating the limestone as mineral alteration into dolomite, which happens due to water evaporation.
Dolomite production and mining in Nigeria:
The production of dolomite in Nigeria as a natural resource dated back to the year 1960. That was actually the period of time when dolomite was discovered in Lokoja, Kogi state for the first time.
Subsequently, the development of Igbeti marble deposits followed suit, before the others were founded as follows: Oreke dolomite of Kawara state, Alagutan dolomite field in Ori Ire, Oyo state, and then the Ikpeshi dolomite despite Edo state, Nigeria.
Dolomite trading in Nigeria:
The trading of dolomite minerals started around the 1970s after its discovery in Nigeria. Up to date, dolomite is still one of the most minerals globally demanded in vast volumes in Nigeria.
Today, Nigeria export dolomite to international suppliers, dealers as well as local buyers across the globe.
General Information about Dolomite:
Dolomite is one of the compositions of limestone that can also be referred to as a sedimentary rock. Both limestone and dolomite behave in similar ways when subjected to heat and pressure.
The composition is therefore, calcium + magnesium + carbonate = dolomite. However, it is chemically classified under carbonate, with the chemical symbol, CaMg (CO3)2.
