Characterisation of surface roughness and wettability of salt-type minerals: calcite and barite
Yekeler, M; Ulusoy, U (MANEY PUBLISHING, 2004)Salt-type minerals of calcium (calcite) and barium (barite) are important raw materials for metallurgical. chemical and algricultural industries. Flotation is the primary process for recovering these minerals from ores. ... -
Correlation of the surface roughness of some industrial minerals with their wettability parameters
Ulusoy, U; Yekeler, M (ELSEVIER SCIENCE SA, 2005)This paper reports the relationships found between the surface roughness and wettability of some industrial minerals, namely, calcite, barite, talc and quartz. These minerals were ground in ball, rod and autogenous mills ... -
Determination of intestinal uptake of iron and zinc using stable isotopic tracers and rare earth markers
Ulusoy, U; Whitley, JE (PERGAMON-ELSEVIER SCIENCE LTD, 1999)Determination of trace element absorption using enriched stable isotopic tracers and faecal monitoring has required 5-10 days collection of faecal output. In this study, the possibility of using rare earths as non-absorbable ... -
Determination of the shape, morphological and wettability properties of quartz and their correlations
Ulusoy, U; Yekeler, M; Hicyilmaz, C (PERGAMON-ELSEVIER SCIENCE LTD, 2003)The distributions of particle sizes and shapes are of great importance to industries employing various materials in powdered form.
