Role of shape properties of calcite and barite particles on apparent hydrophobicity
(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 ...
Determination of the shape, morphological and wettability properties of quartz and their correlations
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
The distributions of particle sizes and shapes are of great importance to industries employing various materials in powdered form. These include many of the raw materials in civil and chemical engineering, pharmaceutical, ...
Effect of particle shape and roughness of talc mineral ground by different mills on the wettability and floatability
(ELSEVIER SCIENCE SA, 2004)
In this study, shape characteristics of talc particles produced by ball, rod and autogenous mills were investigated using Scanning Electron Microscope (SEM) and expressed by the shape descriptors such as elongation, flatness, ...
Kinetics of dry grinding of industrial minerals: calcite and barite
(ELSEVIER SCIENCE BV, 2002)
This paper presents the kinetics study of dry ball milling of calcite and barite minerals. The experimental mill used was a laboratory size of 209 nun diameter, 175 mm length, providing a total 3 mill volume of 6001 Cm, ...
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 ...
Correlation of the surface roughness of some industrial minerals with their wettability parameters
(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 ...
