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 ...
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 ...
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 ...
Variation of critical surface tension for wetting of minerals with roughness determined by Surtronic 3(+) instrument
(ELSEVIER SCIENCE BV, 2004)
This paper presents a correlation found between the surface roughness and critical surface tension of wetting of calcite and barite minerals. The minerals were ground in ball, rod and autogenous mills to collect samples ...
Combination of different size distributions for mineral particles by applying experimentally determined apparent mean shape factor
(TAYLOR & FRANCIS INC, 2008)
As is well known, the behavior of systems of fine particles is strongly dependent on the size of the individual particles, and the size effects become increasingly important as the particles become progressively smaller. ...
A study on spherical oil agglomeration of barite suspensions
(ELSEVIER SCIENCE BV, 2003)
In this study, the recovery of barite particles was investigated by using oil agglomeration. For this purpose, effects of operating parameters were investigated and also, zeta potential measurements and Fourier Transform ...
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 ...
Investigation of relationship between critical surface tension of wetting and oil agglomeration recovery of barite
(ELSEVIER SCIENCE BV, 2004)
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, ...
Flotation responses to the morphological properties of particles measured with three-dimensional approach
(ELSEVIER SCIENCE BV, 2005)
Morphological properties of barite particles ground by autogenous and ball milling were examined by three-dimensional methods, namely, Brunauer-Emmett-Teller (BET) nitrogen adsorption and Permaran methods in terms of surface ...
