Contact angle and surface analysis studies of sphalerite particles

A study on the relationship between critical surface tension of wetting and oil agglomeration recovery of calcite

“…There are limited studies on contact angle measurement for sulfide and nonsulfide minerals to illustrate domains of hydrophobicity and hydrophilicity under a variety of conditions involving pH, collectors, and depressants [15][16][17][18][19][20].…”

Effect of dispersed phase viscosity on solid-stabilized emulsions

“…However, those methods are often found to be inadequate when dealing with porous solid particles (Prestidge and Tsatouhas, 2000;Buckton et al, 1995). Capillary rise techniques have also been proposed (Quere, 1997;Siebold et al, 1997Siebold et al, , 2000Subrahmanyam et al, 1996;Wolfrom et al, 2002) but always with some limitations such as the structure of the solids bed inside the capillary, the experimental requirements, the accuracy, the unknown solids structure inside the bed, its porosity, and many others.…”

Effect of Surface Properties of Iron Ores on their Granulation Behavior

“…The range of the early stage of penetration was neglected since it is governed by inertial forces with very fast rates of liquid uptake, expanding the range of calculations beyond 150 s results in high errors in contact angle determination due to increasing deviation from linearity, Table 1 shows contact angles of four iron ores calculated by formula (1).
