International Journal of Mining Science and Technology
The test coal samples were collected from the Ji 15 –31070 coal seams in the No. 12 mining area of Pingdingshan, Henan Province. After air drying, the coal samples were crushed with an XQM-0.4 planetary ball mill and sieved through a 200 mesh to prepare the test coal dust with a less than 0.075 mm particle size.

Flotation | Mineral Processing, Separation & Beneficiation
Richard Tilghman Weidner Laurie M. Brown. Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to.
Mechanisms of failure in coal samples from underground water reservoir

The Hydrophobic Effects: Our Current Understanding
In general, hydrophobicity is expressed through the empirically calculated logarithm of partition coefficient (logP), which is widely used in drug design and medicinal chemistry [6,7]. Historically, the concept of hydrophobicity arose in the context of the low solubility of non-polar solutes in water. Experimentally, it has been found that the ...

Hydrophobicity
Cid et al. (1992) generated hydrophobicity profiles for several proteins using the surrounding hydrophobicity scale (Ponnuswamy et al. 1980) and derived general rules for identifying secondary structures.The hydrophobicity profiles for α-helices, buried and exposed β-strands and turns are shown in Figure 5.4.The following facts have been …
Microparticulation by Jet Mill Grinding of Protein Powders …
A jet mill produced particles <3 μm from egg white, casein and soybean hull. Microparticulation by grinding of egg white was easier than with casein or soybean hull. Hydrophobicity of casein increased by grinding to super fine particles but little or no effect was observed on soybean hull and egg white.
