Ahiler (Sivihisar-Eskişehir) sepiyolitinin jeokimyasal özellikleri

Çoban, Fazlı (2001)

Sivrihisar göl baseninde alkalin ve tuzlu ortam koşullarında oluşmuş Neojen sepiyolit yatakları bulunmaktadır. Bölgedeki sepiyolitler başlıca üç tiptir, 1) Organik madde yönünden zengin siyah sepiyolitler, 2) Organik madde ...

Application of generalized regression neural networks in predicting the unconfined compressive strength of carbonate rocks

Ceryan, Nurcihan; Okkan, Umut; Kesimal, Ayhan (Springer Wien, 2012)

Measuring unconfined compressive strength (UCS) using standard laboratory tests is a difficult, expensive, and time-consuming task, especially with highly fractured, highly porous, weak rock. This study aims to establish ...

Application of soft computing methods in predicting uniaxial compressive strength of the volcanic rocks with different weathering degree

Ceryan, Nurcihan; Samui, Pijush (Springer Heidelberg, 2020)

Uniaxial compressive strength (UCS) of rock material is very important parameter for rock engineering applications such as rock mass classification, numerical modelling bearing capacity, mechanical excavation, slope stability ...

Application of Support Vector Machines and Relevance Vector Machines in Predicting Uniaxial Compressive Strength of Volcanic Rocks

Ceryan, Nurcihan (Pergamon-Elsevier Science Ltd, 2014)

The uniaxial compressive strength (UCS) of intact rocks is an important and pertinent property for characterizing a rock mass. It is known that standard UCS tests are destructive, expensive and time-consuming task, which ...

Bacterial leaching of coal for the removal of pyritic S

Göktepe, Ferihan; Pooley, Frederick D. (2006)

Most commonly used microorganisms are Thiobacillus Ferrooxidans and Thiobacillus Thiooxidans, which have been shown to be effective in the removal of pyritic sulphur from coal. This study presents the results of bacterial ...

Beneficiation of quartz waste by flotation and by ultrasonic treatment

Göktepe, Ferihan; İpek, Halil; Göktepe, Mustafa (Oficyna Wydawnicza Politechniki Wroclawskiej, 2011)

Quartz is one of the most important industrial minerals used in glass and ceramic industries and high quality quartz are preferred. Impurities from quartz are usually removed by magnetic separation or flotation. This study ...

Classification of dimension stone wastes

Karaca, Zeki; Pekin, Abdülkerim; Deliormanlı, Ahmet Hamdi (Springer Heidelberg, 2012)

For countries in which the stone industry is well developed, opposition to quarry and plant waste is gradually increasing. The primary step for waste control and environmental management is to define the problem of concern. ...

A comparative study on the estimation of shear strength of rock masses using rock SSPC system and Hoek-Brown criterion

Tüdeş, Şule; Ceryan, Nurcihan (2011)

The shear strength of rock masses has vital importance for geotechnical projects such as slope stability, foundation and tunnels. The shear strength of the jointed rock mass can be estimated by different methods including ...

Concentration of K-feldspar from a pegmatitic feldspar ore by flotation

Karagüzel, Cengiz; Gülgönül, İlhan; Demir, Cengiz; Çınar, Mehmet Ulaş; Çelik, Mehmet S. (Elsevier Science Bv, 2006)

Abundant reserves of Na-feldspar (albite) and K-feldspar (orthoclase or microcline) are found in granites, syenite, tracite and pegmatites. As both feldspar minerals have similar chemical structure and physicochemical ...

Determination of grindability characteristics of zeolite

İpek, Halil; Göktepe, Ferihan (Oficyna Wydawnicza Politechniki Wroclawskiej, 2011)

In this study grindability of zeolite was studied. The work index of zeolite was determined for three different test sieves. In terms of work indexes, there was insignificant difference between the test sieves. Additionally, ...

Differential separation of albite from microcline by monovalent salts in HF medium

Demir, Cengiz; Gülgönül, İlhan; Bentli, İsmail; Çelik, Mehmet S. (Soc Mining Metallurgy Exploration Inc, 2003)

Na-feldspar (albite) and K-feldspar (microcline or orthoclase) are major feldspar minerals with identical crystal structures and physico-chemical properties. Flotation appears to be a unique method of separating these ...

Effect of crystallinity and surface silanol groups on rheological properties of different sepiolites
