The effect of inorganic agents on the flotation of barite and fluorite

A probabilistic design approach for rock slopes DUZGUN, HSB; Karpuz, Celal; Yücemen, Mehmet Semih (1998-10-09) The basic aim of this study is to develop a reliability-based methodology for the practical design of rock slopes. The advanced first-order second-moment (AFOSM) approach is adapted as;the reliability assessment model. In the reliability-based design methodology, the first step is the modeling and quantification of uncertainties associated with the design parameters. Since the safety of a rock slope is most sensitive to the shear strength of discontinuities, the uncertainty analysis is focused on the parame...
Modeling of Three Flat Coal Seams Strata Developing at Open Pit Miming GVOZDKOVA, Tatiana; MARKOV, Sergey; Demirel, Nuray; ANYONA, Serony (EDP Sciences; 2017-11-22) The use of low-cost direct dumpling technology, as is well known, has a relatively limited field of application: flat coal seams, and the higher the dip angle of the seam, the more difficult it is to place the necessary volume of overburden rock in the dumping layers. For this, we have to pour four-tier dumps. In this article, four possible options for piling the dump have been studied and prerequisites have been made for further research aimed at improving the efficiency of the use of direct dumpling techn...
Separation of ultrafine particles from class F fly ashes Acar, Ilker; Robl, Thomas L.; Atalay, M. Umit (EDP Sciences; 2016) In this study, ultrafine particles were recovered from Catalagzi (CFA) and Sugozu (SFA) thermal power plant fly ashes using a specific hydraulic classification technology. Since fly ashes have a high tendency to be flocculated in water, settling experiments were first designed to determine the more effective dispersant and the optimum dosage. Two different types of the superplasticizers (SP) polymers based on sulphonate (NSF, Disal) and carboxylate (Glenium 7500) were used as the dispersing agents in these ...
From Mining Innovations to Sustainable Development: Keynote Speakers of the First to the Second International Innovative Mining Symposium CEHLAR, Michal; Janocko, Juraj; Demirel, Nuray; Anyona, Seroni; Voeth, Stefan; TYULENEV, Maxim; ZHİRONKİN, Sergey (EDP Sciences; 2017-11-22) 24-26 April, 2017 the Scientific Practical Conference "International Innovative Mining Symposium (in memory of Prof. Vladimir Pronoza)" was successfully organized at T.F. Gorbachev Kuzbass State Technical University - KuzSTU (Kemerovo Russia). More than 20 participants submitted their papers in presence, and more than 40 authors sent their papers for virtual participation. The main participants of the conference - Keynote Speakers - paid special attention to the development of international cooperation of t...
Assessment of soda ash calcination treatment of Turkish trona ore Gezer, Sibel; Atalay, Umit (2016) Trona is relatively rare, non-metallic mineral, Na2CO3 center dot NaHCO3 center dot 2H(2)O. The pure material contains 70.3% sodium carbonate and by calcination the excess CO2 and water can be driven off, yielding natural soda ash. The terms soda ash and sodium carbonate are used interchangeably. Trona calcining is a key process step in production of soda ash (sodium carbonate anhydrate) from the relatively cheap trona ore. The calcination reaction may proceeds in a sequence of steps. Depending on the condi...
