Application of the Box-Wilson experimental design method for the spherical oil agglomeration of coal
In this study, the Box-Wilson statistical experimental design method was employed to evaluate the effects of important variables such as bridging liquid (oil) concentration, salt (CaCl(2)(.)2H(2)O) concentration and stirring ... -
Effect of the hydrophobic fraction and particle size in the collectorless column flotation kinetics
Yekeler, M; Sonmez, I (ELSEVIER SCIENCE BV, 1997)In order to investigate the particle size effect of a highly hydrophobic mineral (talc), different size fractions were floated in a column flotation cell to obtain the effect of flotation-rate constants (k) on the kinetics ... -
Fundamental aspects of spherical oil agglomeration of calcite
In this study, concentration of calcite particles was investigated using oil agglomeration. For this purpose, effects of operating parameters were investigated and also zeta potential measurements and Fourier transform ... -
Increasing selectivity in coal flotation by controlling impeller speed and collector concentration
Sonmez, I; Akdemir, U; Sahbudak, K (TAYLOR & FRANCIS INC, 2005)Batch flotation experiments were conducted using a bituminous coal. It was found out that pulp density and especially impeller speed had significant influences on coal flotation performance, selectivity and rate. Products ... -
Investigation of coal and ash recovery and entrainment in flotation
Akdemir, U; Sonmez, I (ELSEVIER SCIENCE BV, 2003)This paper discusses the effect of particle size, impeller speed and pulp density on flotation and entrainment of coal and associated gangue, consisting mostly of kaolinite and illite. Experimental work indicated that ... -
The investigation of coal-pyrite/lignite concentration and their separation in the artificial mixture by oil agglomeration
In this study, the concentration of coal-pyrite and lignite taken from Yozoat-Ayridam (Turkey) Coal Management was investigated by oil agglomeration. In the previous studies, the agglomeration of coal-pyrite was investigated ... -
Investigation of relationship between critical surface tension of wetting and oil agglomeration recovery of barite
In this study, relationship between the critical surface tension of wetting of barite and agglomeration recovery and also zeta potential depending on pH and amount of collector (Na-oleate) was investigated. For this purpose, ... -
