Effect of various bridging liquids on coal fines agglomeration performance
(ELSEVIER SCIENCE BV, 2001)
Oil agglomeration is a surface property based on the differences in the surface properties of the organic and inorganic constituents of coal. A bituminous coal was agglomerated using kerosene, diesel oil, Kirkuk Crude ...
Investigation of coal and ash recovery and entrainment in flotation
(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 ...
Performance of classic oils and lubricating oils in froth flotation of Ukraine coal
(ELSEVIER SCI LTD, 2006)
In this study, the appropriate collector and collector amount for Ukraine coal in froth flotation was determined. For this purpose, the performance of classic oils (kerosene, diesel-oil and fuel-oil) and lubricating oils ...
Using float-sink data in simple equations to predict sulfur contents
(ELSEVIER SCIENCE BV, 2002)
In this study, the interpretation of float-sink test data by simple equations on coals of different origins with respect to sulfur content has been investigated. Primarily, the cumulative weight and sulfur content of the ...
Application of the Box-Wilson experimental design method for the spherical oil agglomeration of coal
(ELSEVIER SCI LTD, 2006)
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 ...
Critical solution surface tension for oil agglomeration
(ELSEVIER SCIENCE BV, 2005)
This paper presents the effect of surface tension of solution used as medium for the oil agglomeration of minerals. Naturally occurring hydrophobic and hydrophilic minerals are used in this study. It was determined that ...
Investigation of kinetics of agglomerate growth in oil agglomeration process
(ELSEVIER SCI LTD, 2003)
In this study, the kinetics of agglomerate growth in a batch oil agglomeration process has been studied using bituminous coal. The effect of operating variables such as kerosene concentration, pulp density and speed of ...
