This study was conducted to determine thermal decomposition of gypsum (CaSO4 . 2H(2)O) and celestite (SrSO4), to examine the effect of heating on grindability and the possibility of celestite-gypsum separation by differential grinding after heating. The results indicated that no significant decomposition reaction was observed in celestite up to 900 degreesC whereas the decomposition of gypsum occurred within 100-450 degreesC.

Effect of inlet pressure on crude oil combustion -laboratory approach- Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2021-03-01) In this research, the effect of inlet pressure on combustion behavior of medium and light crude oils was analyzed with TGA and DSC experiments. The ramped temperature combustion experiments were performed at constant heating rates under air atmosphere. TGA curves revealed three main reaction regions known as low temperature oxidation (LTO), fuel deposition (FD), and high temperature oxidation (HTO). In DSC curves, at the early stage of the heating, distillation region was also observed in addition to LTO an...
Quantifying hydrophobicity of pyrite after copper activation and DTPI addition under electrochemically controlled conditions Hicyilmaz, C; Altun, Naci Emre; Ekmekci, Z; Gokagac, G (Elsevier BV, 2004-07-01) In this study, the response of the surface of pyrite to copper activation under electrochemically controlled conditions was investigated in the presence and absence of sodium diisobutyl dithiophosphinate (DTPI). The mechanism of interactions between the concerned reagents and pyrite was investigated using cyclic voltarnmetry in solutions of different pH. In addition, contact angle measurements were performed to determine the wetting behavior of the pyrite surface as a function of pulp potential and pH. The ...
EFFECT OF PHENOL AND RESORCINOL ON LEACHING OF ILMENITE WITH HCL-CH3OH AND HCL-C2H5OH SOLUTIONS GIRGIN, I; Türker, Burhan Lemi; GOODALL, D (Elsevier BV, 1991-07-01) The effects of phenols on hydrochloric acid leaching of metal oxides is investigated theoretically. A mathematical model is developed for the early stages of leaching assuming that steady state conditions and Fick's first law are valid for the formation and diffusion of metal cations through the Helmholtz-Stern interface. It is found theoretically that the leaching rate is exponentially proportional to acid and phenol concentrations and any metal-phenol complex which can be decomposed by chloride ions shoul...
Effect of thermal neutron irradiation on the elastic constants of tourmaline Özkan, H. (Informa UK Limited, 1987-2) The effect of thermal neutron irradiation due to the B10(n, α)Li7 reaction on the elastic wave velocities and the elastic moduli of tourmaline crystals has been studied. Oriented tourmaline samples have been irradiated with thermal neutrons to 7.6 × 1018n/cm2 and the elastic wave velocities determined by ultrasonic measurements. The elastic wave velocities are not affected by thermal neutron irradiation below 8 × 10l7n/cm2, effects starting to appear at approximately 1 × l018n/cm2 with more important decrea...
Effect of surface roughness in microchannels on heat transfer Turgay, Metin Bilgehan; Güvenç Yazıcıoğlu, Almıla; Department of Mechanical Engineering (2008) In this study, effect of surface roughness on convective heat transfer and fluid flow in two dimensional parallel plate microchannels is analyzed by numerically. For this purpose, single-phase, developing, laminar fluid flow at steady state and in the slip flow regime is considered. The continuity, momentum, and energy equations for Newtonian fluids are solved numerically for constant wall temperature boundary condition. Slip velocity and temperature jump at wall boundaries are imposed to observe the rarefa...
