Machine learning models to estimate the elastic modulus of weathered magmatic rocks
(Springer, 2021)In recent years, several soft computing models have been proposed to estimate the elastic modulus of magmatic rocks. However, there are lacks in models that consider the different weathering degrees in determining the ... -
Prediction of Young's modulus of weathered igneous rocks using GRNN, RVM, and MPMR models with a new index
(Science Press, 2021)Young's modulus (YM) of intact rock is an important parameter in the assessment of engineering behaviours of rock masses, and it cannot always be obtained in an economical and practical manner in laboratory experiments. ... -
Application of soft computing methods in predicting uniaxial compressive strength of the volcanic rocks with different weathering degree
(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 ... -
Zeta potential of teflon in presence of monovalent and divalent ions
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2019)In this study, the specific effects of Na+ and Ca2+ ions on natural hydrophobic Teflon particles and flat Teflon surfaces were investigated using zeta potential and contact angle measurements, respectively. The zeta potential ... -
Probabilistic back analysis and their reliabilty of plane failure: A case study from Trabzon-Gumushane highway, NE Turkey
(Stef92 Technology Ltd, 2013)This study discusses the prior information of input data from both laboratory tests and deterministic back calculation methods that are to be considered by probabilistic back analysis method. For this purpose, the failure ... -
Prediction of unconfined compressive strength of carbonate rocks using artificial neural networks
(Springer, 2013)The unconfined compressive strength (UCS) of intact rocks is an important geotechnical parameter for engineering applications. Determining UCS using standard laboratory tests is a difficult, expensive and time consuming ... -
Bacterial leaching of coal for the removal of pyritic S
(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 ... -
A comparative study on the estimation of shear strength of rock masses using rock SSPC system and Hoek-Brown criterion
(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 ... -
Enrichment of pyrite from siirt- Madenköy copper plant tailings by flotation
(2012)Pyrite is present as a gangue mineral in most of complex sulphide ores and most of time it is removed as a tailing. However, beneficiation of pyrite from tailings could be important because of its economical value and for ... -
Probabilistic back analysis of landslides in Arakli-Tasonu quarry, Northeast Turkey
(Elsevier Science Bv, 2015)This study evaluates the landslides that occurred on 3 October 2005, 20 March 2006, and 19 October 2006 in Tasonu Limestone Quarry, Trabzon, and Northeast Turkey. The failure plane of the three landslides occurred on the ... -
Modeling of tensile strength of rocks materials based on support vector machines approaches
(Wiley, 2013)In the predicting of geological variables, artificial neural networks (ANNs) have some drawbacks including possibility of getting trapped in local minima, over training, subjectivity in the determining of model parameters ... -
Evaluation of Turkish bentonite for removal of dyes from textile wastewaters
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2012)Removal of reactive dyes from textile industry wastewaters is a great economic and environmental challenge. In this study, systematic adsorption tests were carried out using natural and modified bentonites to remove a ... -
Interaction of sodium ions with feldspar surfaces and its effect on the selective separation of na- and k-feldspars
(Taylor & Francis Inc, 2012)K-feldspar and Na-feldspar exhibit similar mineralogical, chemical and surface properties. Froth flotation is known to be the only technique to enable their separation. Our earlier studies revealed a good selectivity in ... -
Classification of dimension stone wastes
(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. ... -
Role of starch and metabisuphite on pure pyrite and pyritic copper ore flotation
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2012)Depression of pyrite is very important in sulphide ore flotation. This paper investigates the role of non-toxic depressants on the flotation of pyrite. Starch and meta bisulphite were used as a depressant for pure pyrite ... -
Application of generalized regression neural networks in predicting the unconfined compressive strength of carbonate rocks
(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 ... -
Surface vs. bulk analyses of various feldspars and their significance to flotation
(Elsevier Science Bv, 2008)Cationic separation of Na-feldspar (albite) and K-feldspar (microcline) was earlier reported to be possible in the presence of monovalent salts. However, contrary to this result, the floatability of a series of K-feldspar ... -
Concentration of K-feldspar from a pegmatitic feldspar ore by flotation
(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 ...
