Use of Pinched Sluice in Albite Concentration
(Polish Mineral Eng Soc, 2017)
Albite (NaAlSi3O8) is an important industrial mineral especially for ceramic and glass production. Major Fe-containing impurity of albite ore is flaky mica minerals. This study was conducted to determine the applicability ...
TANNIC ACID AS A HYDROPHOBICITY MODIFIER FOR GALENA IN THE PRESENCE OF METAL IONS
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2017)
This study was performed to determine the effect of tannic acid (TA) on hydrophobicity of galena using Taguchi's design of experimental methodology. Roles of metal ions, dithiophosphinate (DTPI) concentration, and conditioning ...
Potential Response of Pyrite Electrode in the Presence of Metal Ions
(Polish Mineral Eng Soc, 2017)
Potential response of pyrite in an electrochemically active environment was supposed to shed light on its redox behavior in the presence of Cu+2, Pb+2 and Fe+2 ions, the commonly existing metal ions in flotation pulps of ...
Hydrophobicity of Galena with Ovabulbumin and Dithiophospinate in Relatoion to its Potential Response
(Polish Mineral Eng Soc, 2018)
This study was performed to elucidate the role of ovalbumin (OVA) on the hydrophobicity and potential response of galena in the presence of dithiophosphinate (DTPI). OVA was tested as environmentally friendly depressing ...
Investigation of design parameters of a failed soil slope by back analysis
(Pergamon-Elsevier Science Ltd, 2017)
A soil slope instability occurred at the surface facility area of a mine site, which was successfully managed from occupational health and safety point of view, and no human or material loss was encountered. Three different ...
A pick force calculation method suggested for tool lacing of mechanical excavators employing drag tools
(Taylor & Francis Ltd, 2018)
This paper deals with tool lacing design of partial-face cutting machines employed for mechanical excavations of rocks, coal and stones. A rational comparison between relief cutting and groove deepening was made by simulating ...
Investigations into tilt angles and order of cutting sequences for cutting head design of roadheaders
(Pergamon-Elsevier Science Ltd, 2018)
This paper explains optimum arrangement of gauge tools and corner cutting picks for cutting head design of roadheaders. Full-scale simulation of roadheaders cutting heads of practical types with a wide range of tilt angles ...
Performance Prediction of Circular Diamond Saws by Artificial Neural Networks and Regression Method Based on Surface Hardness Values of Mugla Marbles, Turkey
(Pleiades Publishing Inc, 2019)
Sawing of natural stones with diamond-impregnated circular saws is extensively implemented in stone processing plants in variety of applications that include sawing, cutting, splitting and trimming. Hence, the cost of ...
High-temperature electrocoagulation of colloidal calcareo-argillaceous suspension
(Elsevier Science Bv, 2018)
In this work, the temperature-dependent electrocoagulation behavior of the highly stable calcareo-argillaceous colloids was studied. The response surface methodology was implemented to explain the performance of this ...
An investigation on single-particle impact breakage functions of a gold ore by drop-weight technique
(General Directorate of Mineral Research and Exploration (MTA), 2017)
Impact breakage functions for a gold ore from Bergama region (Turkey) was estimated based on the single-particle impact breakage distributions of particles obtained from drop weight tests. For this purpose, a modified ...
