Separation of huntite and hydromagnesite from magnesite in combination of physicochemical treatment and size reduction
(Elsevier Science Bv, 2019)
Huntite and hydromagnesite are important minerals in the synthesizing of fire-safe composites. They are mostly not pure and associated with gangue minerals like magnesite, dolomite, aragonite and calcite. In this study, ...
Redox behavior of galena in alkaline condition
(Springer Heidelberg, 2018)
Electrochemical potential determines types of redox products formed on electrically conducting minerals like galena, which might manipulate process efficiency applied on the target mineral. Therefore, electrochemical ...
Relating rock mass properties with Lugeon value using multiple regression and nonlinear tools in an underground mine site
(Springer Heidelberg, 2019)
The Lugeon test is one of the commonly applied field methods for measuring hydraulic conductivity of a rock mass. Understanding hydraulic conductivity is especially necessary when groundwater is present, as it has a direct ...
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 ...
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 ...
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 ...
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 ...
