Beneficiation of Elazig-Kefdag chromite by Multi Gravity Separator
Gence, Nermin (1999)In this study, the possibility of beneficiation of chromite in the Elazig-Kefdag region by Multi-Gravity Separator was investigated. The results of beneficiation studies showed that commercial concentrate containing 52.14% ... -
Coal recovery from bituminous coal by aggloflotation with petroleum oils
Gence, Nermin (Elsevier Sci LTD, 2006)The objective of this work is to obtain high calorific value/low ash content products from fine bituminous coals by aggloflotation with petroleurr oils such as hexane, heptane, toluene and pentane. The two methods used ... -
Flotation of magnesite with sodium oleate and oleic acid as collector; an infrared spectrophotometric study
Gence, Nermin; ÖzDağ, H. (1993)Infrared spectra studies were carried out in order to interpret and elucidate the adsorption mechanism in the magnesite flotation; also froth flotation tests were carried out. Infrared spectrophotometry studies indicated ... -

pH dependence of electrokinetic behavior of dolomite and magnesite in aqueous electrolyte solutions
Gence, Nermin; Özbay Nurgül (Elsevier Science BV, 2006)In this paper. electrokinetic potential and isoelectric point of dolomite (CaMg(CO3)2) and magnesite (MgCO3) were determined. The effect of various ions such as Mg2+, Ca2+, Na+ and CO32- on surface properties of dolomite ... -
Wetting behavior of magnesite and dolomite surfaces
Gence, Nermin (Elsevier Science BV, 2006)Magnesite and dolomite are salt-type minerals that show similar chemical composition and flotation behavior due to same crystal structure, and sparingly soluble nature. The surface properties of minerals play a major role ...
