Nov 12, 202001-03-2000 Froth images from video were post-processed to determine the bubble size distribution (Sadr-kasemi and Cilliers, 1997) and froth velocity. Calculation of specific surface area in flotation 269 CALCULATIONS The parameter of interest in this work is the specific surface area of the froth, as is used in the Woodburn et al. (1994) model.

maximizes the bubble specific surface area available to particles for attachment. Any dosage higher than the CCC will have no further reducing effect on bubble size and therefore has no further benefit to the pulp phase kinetics. Extra frother (above the CCC dosage) can be added to improve froth stability. Wiese et al. (2011) found that

Abstract. Different weighting functions for calculating the specific surface area and average bubble diameter in froth flotation have been studied. The weighting functions considered were number, length, area and volume. Using bubble size distribution data obtained from image processing of batch flotation froth, specific surface area and

The Specific Surface Area (SSA) of bare liner is easy to calculate. Simply calculate the square footage of each of the surfaces in a pond. Here is an example of a rectangular shaped, bare liner Koi pond that is 20 feet long by 10 feet wide by 5 feet deep. First calculate the square footage of the bottom of the pond. 20' x 10' = 200 square feet.

Thus, 1440 x 0.32 equals 461 square inches of drum surface, which equates to 77 square inches of contact area for each of the six supporting floats (461/6 equals 77). Since each float must have contact with at least two cross-members of the structure, each cross-member should have at least 38.5 square inches in contact with the float (77/2

Specific surface area (SSA) is a property of solids defined as the total surface area of a material per unit of mass, (with units of m 2 /kg or m 2 /g) or solid or bulk volume (units of m 2 /m 3 or m −1).. It is a physical value that can be used to determine the type and properties of a material (e.g. soil or snow).It has a particular importance for adsorption, heterogeneous catalysis, and
