A new microscale flotation cell: Combination of Canadian column and Partridge-Smith cell
Ozkan, A; Yekeler, M (KOZAN OFSET MALBAACILIK SAN VETIC LTD STI, 2001)Flotation is one of the most important physicochemical processes for mineral separations and other recovery operations. Flotation machines have been developed since the beginning of the 19(th) century and are still under ... -
Prediction of the wettability characteristics of some minerals from their breakage parameters
Yekeler, M; Ozkan, A (ELSEVIER SCIENCE BV, 2003)In this contribution, the breakage and wettability properties of calcite and barite minerals were presented and some correlations were established between these experimentally determined parameters. The gamma(c) relates ... -
Reactivities of some thiol collectors and their interactions with Ag (+1) ion by molecular modeling
Yekeler, H; Yekeler, M (ELSEVIER SCIENCE BV, 2004)The most commonly used collectors for sulfide minerals in the mining industry are the thiol collectors for the recovery of these minerals from their associated gangues by froth flotation. For this reason, a great deal of ... -
Relationship between the breakage and wetting characteristics of lignite
Yekeler, M; Ozkan, A (NATL INST SCIENCE COMMUNICATION, 2002)This paper reports the findings of an investigation of the breakage values of lignite to relate the wettability properties. The breakage values, obtained from grinding, are the specific rates of breakage (S-i) and the gamma ... -
Role of shape properties of calcite and barite particles on apparent hydrophobicity
Ulusoy, U; Hicyilmaz, C; Yekeler, M (ELSEVIER SCIENCE SA, 2004)Shape properties of calcite and barite particles ground by ball, rod and autogenous mills were examined by using scanning electron microscope (SEM). Shape properties have been stated in terms of shape descriptors such as ... -
Shear flocculation of celestite with sodium oleate and tallow amine acetate: effects of cations
Ozkan, A; Yekeler, M (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004)Sodium oleate and tallow amine acetate (TAA) were used as surfactants for the shear flocculation of celestite. The shear-flocculation power values obtained with sodium oleate were higher than those obtained with TAA in ... -
Variation of critical surface tension for wetting of minerals with roughness determined by Surtronic 3(+) instrument
Ulusoy, U; Yekeler, M (ELSEVIER SCIENCE BV, 2004)This paper presents a correlation found between the surface roughness and critical surface tension of wetting of calcite and barite minerals. The minerals were ground in ball, rod and autogenous mills to collect samples ... -
Wettability characteristics of sparingly-soluble minerals: Fluorite, calcite and apatite
Yekeler, M; Yarar, B (A A BALKEMA, 1996)…
