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 ... -
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 ... -
Application of Support Vector Machines and Relevance Vector Machines in Predicting Uniaxial Compressive Strength of Volcanic Rocks
(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 ... -
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. ... -
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 ... -
Effects of bivalent salts on the flotation separation of Na-feldspar from K-feldspar
(Pergamon-Elsevier Science Ltd, 2003)Despite similarities in the physical and physico-chemical properties of Na- and K-feldspars, their flotation separation with monovalent ions exhibited a reasonable success. Further studies have been therefore initiated to ... -
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 ... -
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 ... -
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 ... -
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. ... -
A study of surface morphology of small magnesite ore blocks using numerical computations
(Gebruder Borntraeger, 2016)Determination of morphological structure of natural ore is an important concept. Although there are many studies related to the determination of the chemical structure of minerals, there has not been much work about the ... -
Treatment of lead mine waste by a Mozley multi-gravity separator (MGS)
(Academic Press Inc Elsevier Science, 2005)Increasing environmental awareness and pressure is focusing attention on metal removal leading to the accelerated development of contaminated land reclamation technologies. The majority of wastes associated with base metal ... -
Understanding the flotation separation of Na and K feldspars in the presence of KCl through ion exchange and ion adsorption
(Pergamon-Elsevier Science Ltd., 2018)Flotation is the only technique that enables the selective separation of Na and K feldspar minerals from each other. In this study, the flotation separation of Na-feldspar (albite) and K-feldspar (microcline) minerals were ...
