The Usability of clay deposits in Çankırı and Afyonkarahisar for pelotherapic applications

Aytaç Okyay, Gözde
Thermotherapy using natural thermal mud has played a crucial role for human health care since ancient times. However, recently the SPA and Wellness Centers have come into prominence with the exhaustion of primary reserves of natural thermal mud. In these centers, instead of natural thermal mud, peloids prepared using clay and/or clay minerals with thermal or mineral water through maturation process that changes the physicochemical properties of the clay and/or clay minerals. Turkey has several clay reserves; however, the investigation about their suitability for the pelotherapic applications is not adequate. The aim of this study is to investigate the mineralogical, chemical, and physicochemical properties of the 13 different samples collected from Küçükhacıbey, Hancılı, and Kazbekir localities in Çankırı and Kızılören, Karadirek, and Hüdai localities in Afyonkarahisar in order to evaluate their suitability for pelotherapic applications. The results of mineralogical, chemical, and physicochemical analyses including cation exchange capacity, swelling index, plastic index, water loss, specific surface area, grain size and cooling rate properties were compared with the results in the previous studies. For maturation process distilled water and two different commercial mineral water with different chemical compositions were used. At the end of the four week long maturation, the peloids are evaluated in the sense of consistency, ease of handling and pleasant sensation during application. Evaluation of analyses results showed that clay deposits in Hancılı and Küçükhacıbey localities in Çankırı can be considered being suitable for pelotherapic applications. On the other hand, clay deposits in Kazbekir locality in Çankırı and in all three localities in Afyonkarahisar cannot be considered being suitable for pelotherapic purposes.


Numerical modeling of seawater groundwater relationships in the Selçuk sub basın, İzmir Turkey
Hassan, Abubakr; Çamur, Mehmet Zeki; Department of Geological Engineering (2004)
Seawater-fresh groundwater natural equilibrium conditions in the aquifers of the Selçuk sub-basin may be disturbed by the discharge occurred during the past 30 years in order to supply water for irrigation and domestic purpose usage. Two dimensional density dependent cross sectional saturated flow and solute transport simulations were carried out to determine whether seawater intrusion has occurred in the Selçuk sub-basin due to the imposed discharge or the determined salt-water in the western section of th...
A decision support system for electricity generation investment
Alpagut, Merih Ayşe; Güyagüler, Tevfik; Department of Mining Engineering (2010)
In the recent years, ongoing debates in the mineral sector has shown that efficient use of natural resources is of vital importance as the use of minerals is essential for modern living. Especially, in the context of sustainable development, it is required that mineral resources should be exploited to maximize the contribution to the well being of current generation without depriving the potential for future generations to meet their own needs. The aim of this thesis is to develop a decision support system ...
Characterization of clay rock samples of a borax ore in relation to their problematical flocculation behavior
ÇIRAK, MUSTAFA; Hoşten, Çetin (2015-11-01)
Beneficiation process in the Kirka Borax Concentrator in Turkey generates a tailings effluent containing 3-10% solids that are composed mainly of colloidal particles of clay-rock-type gangue minerals and some unrecoverable borax fines. These colloidal particles form very stable aqueous suspensions in the tailings, hindering solid/liquid separation and clean water recovery. This leads to difficulties in the sustainable and environmentally acceptable operation of the concentrator. Flocculation studies on thes...
Management of disalination brine in Qatar and the GCC countries
Sezer, Nurettin; Evis, Zafer; Koç, Muammer (null; 2017-06-30)
Reliance on desalinated water has been ever-increasing due to increase in population and over-exploitation of natural fresh water resources. Desalination process produces fresh water at the expense of natural environment. Desalination waste, known as brine, is the major pollutant of seawater. However, there has not been a unique brine management technology that could work effectively everywhere. Therefore, effective processes are required to treat and manage the brine specific to the desalination plants. In...

The effects of various thermal treatments on the properties of both PEEK and APC2 have been systematically studied. X-ray diffraction data, together with dynamic mechanical measurements, indicate that the T(g) values for both materials are considerably higher than those generally reported. Also, the tan delta values for quenched APC2 specimens are considerably higher than for slowly cooled materials. Microstructural observations show that this is likely to be due to poor fibre/matrix adhesion, in the case o...
