This study investigated calcination behavior of one of the Turkish laterite deposits, which was recently found in Sivrihisar region. Representative limonitic laterite samples (1.26% Ni) taken from Yunusemre Karasivritepe and Kucuksivritepe location were first subjected to drying. Removal of chemically bound water and other volatiles were then studied, in detail. In the calcination experiments, temperature and time were the main experimental variables. Thermal treatment was conducted at the specific temperatures in 250 degrees C - 800 degrees C range. The weight losses due to elimination of chemically bound water and other volatiles were reported to be approximately 10 per cent of the weight of the ore. For the particle size used in the current work, 700 degrees C and 40 minutes were determined to be the optimum calcination temperature and time, respectively.

Reactivity of limestones from different sources in Turkey Hoşten, Çetin; Gulsun, M (Elsevier BV, 2004-01-01) This paper presents a study on the reactivity of natural limestones from five deposits in Turkey. The conversion rates of carbonates in size fractions of the samples were measured in a stirred suspension of 2.5 1 at 20 degreesC and a constant-pH value of 5 obtained with the addition of HCl solutions by a pH control pump. Particle size and the dolomite content of the limestones were found to be the most influential parameters in the reactivity measurements.
Extraction of zinc from smithsonite by ammonia leaching TALAN, DENİZ; ATALAY, MUSTAFA ÜMİT; Altun, Naci Emre (2017-06-11) – In this study, an ore taken from Kayseri region of Turkey was used. Characterization studies showed that the run-of mine ore is rich in oxide minerals, cerussite (PbCO3) and smithsonite (ZnCO3). The aim of the study was extraction of zinc from smithsonite by ammonia leaching on cerussite flotation tailings. Initial lead and zinc grades of the ore were 13.31% and 27.86%, respectively. As a result of a series of cerussite flotation tests, a lead concentrate containing 63.25% Pb was produced with 82.76% reco...
Ionic composition of aerosols at Northwestern Turkey Tokgoz, Deniz D. Genc; Dogan, Guray; Ilhan, Ali Ihsan; Balta, Tulay; Tuncel, Süleyman Gürdal (2015-01-01) In this study, ionic compositions of 350 aerosol samples collected between April 2006 and May 2008 in a rural area at Northwestern Turkey (Black Sea coast of Turkey) were discussed. Ions accounted for approximately 30% of PM mass. Contributions of secondary aerosol species (NO3-, SO42- and NH4+) were higher than the ions with crustal origin. This indicated that sampling station was under the influence of long range transport because there were no industrial emissions around. Concentrations of ions demonstra...
Kinetic analysis of central anatolia oil shale by combustion cell experiments Iscan, A. G.; Kök, Mustafa Verşan; Bagci, A. S. (Springer Science and Business Media LLC, 2007-06-01) In this study, four oil-shale samples (Nigde-Ulukisla) excavated from Central Anatolia Turkey were analyzed where this region is believed to have a high potential of oil in its shale rich outcrops. The samples (similar to 40 g) were combusted at 50 psi gas injection pressure, at an air injection rate of 1.5 L min(-1) in a combustion-reaction cell. All the experiments were conducted up to 600 degrees C. The percentages of oxygen consumption and carbon monoxide and carbon dioxide production were obtained inst...
Reaction chemistry of gold leaching in thiourea solution for a Turkish gold ore Orgul, S; Atalay, U (Elsevier BV, 2002-12-01) This study was carried out on a finely disseminated gold-bearing ore from Kaymaz, Turkey. The main objective was to determine the mechanism of reaction between thiourea and Fe 31 in the thiourea leaching of gold. Thiourea consumption levels were also examined during the leaching operations for different leaching parameters, i.e., molar ratio of ferric sulfate/thiourea, pH, and temperature. The leaching using the thiourea process was compared with cyanidation. In optimum leach conditions, 85.8% gold extracti...
