UMTAS Uluslararasi Madencilik A.S.
List Global Trade invest %40 Stock Shares of the Gaziantep Nurdağı Chrome Mine Field.
We have been meeting the challenges of the mining sector and contributing to the economy by extracting Turkish richness from the ground. We, Umtas Madencilik is the actual owner of Gaziantep, Nurdağı Chrome Mine Field.
Umtas Mining has always worked and continues to work according to our misson: ‘Interpret Turkish richness on the ground and underground and leave a value to the future’.
The mining license site, defining the work area is situated at the “Gaziantep province – Nurdağı county, Kömürler village” region, approximately between Kömürler, Çakmak and Incesu villages of Nurdağı county and at a distance of 62 km to Gaziantep city, and 7 km to Nurdağı settlement (Figure 2). The Gaziantep – Osmaniye highway is passing through the site and one access into the license site via unpaved roads departing from highway.
We are proud to maintain our position as one of the leading mining companies in Turkey through our philosophy to ‘respect the environment with modern operations’
The part of Islahiye plain suitable for agricultural usage and with a quite broad topography, remaining at the north of the Gaziantep – Osmaniye highway and the presently rugged zone devoid of herbs in general remaining at the south of the highway present distinct surface outlooks. The heights reaching a maximum at the central area of southern section descend anew towards further south.
Chrome and chromite in Turkey
Turkey is one of the foremost countries, producing chromite ore which is among the important raw materials of today's technology and having the particularity of metallic mine most available in our country and of which the sale is accomplished most. in While the Turkish chrome mining has started at Ottoman era, not much document is at hand regarding to chrome mining, pertaining to the period, prior to the foundation of MTA and Etibank. It is understood from the vestiges belonging to the ancient era, that the exploitations are carried out under the form of exposed exploitations close to coastal line, at locations to which access is easy and where big croppings are situated, and that chrome prospection is realized with the intention of discovery of croppings disposing desired properties.
The chrome prospection in Turkey can be described, up to the 1950's as encountering chromite formations which have distinct croppings on the surface and to recognize them. As for the exploitations, it seems that they are depending on the thicknesses grades and traceable continuities of chromite bands and lenses, are based upon cropping mining and open exploitation of which the depth is not more than a few of tens of meters in general. The exploitation of chrome deposits through underground mining methods have gradually increased from the 1960's onwards, in view of the chrome deposits of which the lengths are usually in the vicinity of a few of ten of meters and annual productions are at the level of a few thousand tons and a few tens of thousand tons that can be exploited through open exploitation methods have gradually decreased. Currently, the opportunity to find untouched chrome croppings having exploitable properties in Turkey is quite restricted. The number of chrome deposit that may be operated through open exploitation is also lower in comparison to the past.
Nowadays various underground mining production methods are being implemented depending on lengths and continuities of chromatid bands and lenses, making up chrome deposit. While the ramble (cut and fill) method is the most widely applied production method, room and pillars method in general or distinct methods, called as top slicing with artificial roof as is the case in Çamaşırlık (Mihalıçcık – Eskişehir) mine are put into practice at sections where the chromatid bands and lenses are thick and of which their continuity is considerable.
