Effect of operational conditions on energy efficiencies of air-swept ball mill and classification circuits in cement raw material production
(Baski, 2019)
Operational performance and energy efficiencies of cement raw material grinding air-swept ball mill and classification circuits were analysed and discussed in this study. Extensive sampling surveys were performed around ...
Quartz bleaching by oxalic acid: Relationship between rejection rate of impurities and color response
(Baski, 2019)
Quartz beneficiation has been applied to meet market requirements by physical and/or chemical methods. Chemical beneficiation has long been investigated by inorganic (e.g. sulfuric acid) and organic (e.g. oxalic acid) ...
Predicting the relationships between brittleness and mechanical properties (UCS, TS and SH) of rocks
(Academic Journals, 2010)
This paper presents the evaluation of uniaxial compressive strength (UCS) predicted from Shore hardness (SH) tests and to correlate brittleness concepts, which are derived from UCS, tensile strength (TS) and Shore hardness ...
INCIDENTAL RELEASE OF BITUMEN DURING OIL SHALE GRINDING AND IMPACTS ON OIL SHALE BENEFICIATION
(Estonian Academy Publishers, 2009)
The particle surface characteristics of oil shale and the changes in these characteristics with increasing fineness were determined. FTIR and electro-kinetic studies showed that the surfaces of oil shale particle were ...
Assessing Rock Mass Permeability Using Discontinuity Properties
(Elsevier Science Bv, 2017)
Field measurement of rock mass permeability is essential that numerous factors influence its directional magnitude. Lugeon test is a popularly conducted field instrument in order to measure hydraulic conductivity of a rock ...
Advances on the fragmentation-energy fan concept and the swebrec function in modeling drop weight testing
(MDPI, 2021)
The breakage index equation (BIE), or t10 model from drop weight testing (DWT) data for rocks and ores is used in the design of crushers and mills. Such models are becoming increasingly difficult to visualize as the number ...
Combined effect of pyrometallurgical and hydrometallurgical processes on quartz ore purification
(Chamber of Mining Engineers of Turkey, 2021)
Recent advances in high-tech applications have highlighted the growing demand on highly pure silicates like quartz. Therefore, purification of quartz ore was determined as the subject of this study performed by pyrometallurgical ...
AŞIRI DEFORMASYONA MARUZ KALAN GALERİDE ÇOK KATMANLI TAHKİMAT SİSTEMİNİN UYGULANMASI
(Baski, 2019)
Underground mine openings are driven by installation of light supports as possible as engineering norms dictate. It is possible to ensure adequate advance rates and cost by employing such light support systems. If the ...
