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 ...
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 ...
Dry grinding kinetics of binary mixtures of ceramic raw materials by Bond milling
(ELSEVIER SCI LTD, 2005)
The kinetics of batch dry grinding of binary mixtures of ceramic raw materials, namely quartz-kaolin, quartz-potassium feldspar and kaolin-potassium feldspar, from the feed sizes of -3.350 + 2.360, -2.000 + 1.400, -0.850 ...
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 ...
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 ...
Reactivities of some thiol collectors and their interactions with Ag (+1) ion by molecular modeling
(ELSEVIER SCIENCE BV, 2004)
The most commonly used collectors for sulfide minerals in the mining industry are the thiol collectors for the recovery of these minerals from their associated gangues by froth flotation. For this reason, a great deal of ...
Kinetics of fine wet grinding in a laboratory ball mill
(ELSEVIER SCIENCE SA, 2001)
The kinetics of batch wet grinding of quartz from a feed of 600 x 425 mum to a product of 80% less than 8 mum have been determined using sieving and laser diffractometer sizing for size analysis. A dispersing agent was ...
