Results of experiments on the briquetting of Tuncbilek lignite fines using ammonium nitrohumate (anh), a low calorific value, young lignite-derived humic acid salt solution, are reported. The particulate material was blended with ammonium nitrohumate serving as the binder. In the briquetting tests, the effects of moisture content, pressure, binder content, nitrogen content and heat treatment were investigated. Durable briquettes, in ternis of mechanical strength and water resistance, were produced with a 7% binder content at 10.5% moisture, following pressing at 1280 kg/cm(2) and drying at 165degreesC for 1 h. The briqueues produced with ammonium nitrohumate had better combustion properties than run-of-mine samples; the contribution of the binder to smoke and sulphur emissions was very low and fine dust particles were negligible.

Electrochemical behaviour of chalcopyrite in the absence and presence of dithiophosphate Güler, Taki; Hiçyılmaz, Cahit; Gökağaç, Gülsün; Ekmekçi, Zafir (Elsevier BV, 2005-02-07) Electrochemical behaviour of chalcopyrite was investigated in collectorless condition and in the presence of dithiophosphate (DTP), which is a selective collector for chalcopyrite, by cyclic voltammetry (CV) study. Diffuse Reflectance Infrared Fourier Transformation (DRIFT) spectroscopy was employed to identify surface species of DTP at chalcopyrite surface. CV tests established the certain degree of irreversibility in the absence of DTP possibly due to preferential dissolution of iron ions in slightly acid...
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...
A novel laboratory procedure for predicting continuous centrifugal gravity concentration applications: The gravity release analysis Sakuhuni, G.; Altun, Naci Emre; Klein, B.; Tong, L. (Elsevier BV, 2016-09-10) A novel procedure, Gravity Release Analysis (GRA), is introduced for performance prediction of continuous centrifugal concentration, using lab-scale batch tests. Also, linked with the GRA, the Gravity Release Index (GRI) was developed for ranking the ore amenability to centrifugal gravity concentration. Ore samples from the flotation circuit of Myra Falls concentrator were subjected to Multi Pass Test and Gravity Amenability Test for comparison with GRA. Recovery kinetics of batch centrifugal concentration ...
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...
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.
