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.

Hydrometallurgical processing of nontronite type lateritic nickel ores by MHP process Kose, C. H.; Topkaya, Yavuz Ali (Elsevier BV, 2011-04-01) The research work presented in this paper determined the optimum conditions at which nickel and cobalt could be obtained at maximum efficiency from the column leach liquor of the lateritic nickel ore existing in Gordes region of Manisa in Turkey by performing effective hydrometallurgical methods. This column leach solution was initially neutralized and purified from its basic impurities by a two-stage iron removal process, nickel and cobalt were precipitated in the form of mixed hydroxide precipitate from t...
Seismically induced landslide at degirmendere nose, Izmit Bay during Kocaeli (Izmit)-Turkey earthquake Çetin, Kemal Önder; Unutmaz, B (Elsevier BV, 2004-04-01) This paper presents a study on the analyses of seismically induced landslide at Degirmendere Nose during the 1999 Kocaeli (lzmit)-Turkey earthquake. The paper discusses: (1) observed ground deformations and displacements after the earthquake, (2) the results of field investigations by means of borings and in situ index tests including standard penetration tests, static cone penetration tests (CPT) and piezocone tests, (3) analyses of observed landslide mechanisms by a suite of methods and (4) potential effe...
Adsorption of dithiophosphate and dithiophosphinate on chalcopyrite Guler, T; Hicyilmaz, C; Gokagac, G; Ekmeci, Z (Elsevier BV, 2006-01-01) Electrochemical behavior of chalcopyrite was investigated in the absence and presence of dithiophosphate (DTP) and dithiophosphinate (DTPI), selective thiols against Fe-sulfides in the flotation of sulfide ores, in potentiostatically controlled electrochemical condition. Diffuse reflectance Fourier transformation (DRIFT) spectroscopy was applied to determine the type of adsorbed collector species, and Hallimond tube flotation tests were performed to clarify the role of polarization potential and thiol colle...
Extraction of cobalt and copper from Küre pyrite concentrate Çokgör, O.; Topkaya, Yavuz Ali (Elsevier BV, 1988) Three methods were investigated for the extraction of cobalt, copper and gold from Kure pyrite concentrate. These were chloridizing roasting, chloridizing volatilization and sulphating roasting processes. For chloridizing roasting, the pyrite concentrate was dead roasted first to adjust sulfur content to about 4%. Then, the pyrite cinder obtained was mixed with NaCl and pyrite concentrate, and roasted to produce soluble chlorides of copper and cobalt. For chloridizing volatilization, copper, cobalt and g...
Effect of heat treatment on grindabilities of celestite and gypsum and separation of heated mixture by differential grinding Sener, S; Bilgen, S; Ozbayoglu, G (Elsevier BV, 2004-03-01) 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.
