A new microcolumn flotation cell for determining the wettability and floatability of minerals
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2003)
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 19th century and are still under ...
Coagulation and flocculation characteristics of celestite with different inorganic salts and polymers
(ELSEVIER SCIENCE SA, 2004)
Coagulation and flocculation characteristics of celestite were investigated using CaCl2, MgCl2 and AlCl3 and anionic (A-150), cationic (C-573) and non-ionic (N-100) flocculants, respectively. Isoelectric point of celestite ...
Breakage parameters of some minerals and coals ground in a laboratory size ceramic mill
(NATL INST SCIENCE COMMUNICATION, 2003)
The kinetics of batch dry and wet grindings of calcite, barite, quartz, lignite and anthracite from feeds of sieve size 425+300 mum has been determined using a laboratory scale ceramic ball mill. The S-l values obtained ...
Relationship between the breakage and wetting characteristics of lignite
(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 ...
Correlation of the breakage parameters with the critical surface tension for wetting of barite
(ELSEVIER SCIENCE SA, 2003)
In this paper, we present a correlation and experimental data for a relationship between the breakage and the wettability for barite mineral. The breakage parameters, which are readily obtained from grinding test, are the ...
Prediction of the wettability characteristics of some minerals from their breakage parameters
(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 ...
Fine dry grinding of zeolite in a laboratory ball mill
(WILEY-V C H VERLAG GMBH, 2003)
This paper presents the importance and usage of natural zeolites, which was recently recognized in the industry. Therefore, the grinding properties of natural zeolite were studied with the emphasis on a kinetic study in a ...
Kinetics of wet versus dry grinding of lignite by a porcelain mill
(NATL INST SCIENCE COMMUNICATION-NISCAIR, 2002)
The kinetics of dry versus wet grinding of several feed size fractions of lignite in a laboratory size porcelain mill are reported here using feed fractions prepared to 600+425, -425+300 and -300+212 mum mono-sizes. The ...
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 ...
Shear flocculation of celestite with sodium oleate and tallow amine acetate: effects of cations
(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 ...
