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, ...
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 ...
Influence of shape characteristics of talc mineral on the column flotation behavior
(ELSEVIER SCIENCE BV, 2006)
Column flotation, which is a very effective process in mineral processing especially for easily floatable minerals, is one of the most important new developments to emerge in mineral processing technology in the last years. ...
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 ...
Floatability of barite particles with different shape and roughness
(NATL INST SCIENCE COMMUNICATION, 2007)
In this article, different mill (ball, FOCI and autogenous) products of barite mineral were characterized in terms of their shape., roughness and wettability. 2D shape parameters were measured by the particle projections ...
Response of rough and acute surfaces of pyrite with 3-D approach to the flotation
(CONSULTANTS BUREAU/SPRINGER, 2006)
This study presents a new 3-D approach to determine the morphological properties of pyrite particles by Brunauer - Emmett - Teller (BET) nitrogen gas adsorption and Permaran methods. The obtained parameters, which are ...
Characterisation of surface roughness and wettability of salt-type minerals: calcite and barite
(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. ...
