Specific surface area - Wikipedia

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 ...

Effect of Coarse Particles in Mineral Flotation - AusIMM

Flotation behaviour can be controlled, due to diminishment of granula quality and extension of specific surface area, by adding coarse particles (high- grade concentrates) to condition pulp. It has been substantiated that coarse particles can intensify fine particle flotation and its mechanisms are effects of carrier, intermedium and assistant aggregation of coarse particles. Calculation and...

1 Froth Flotation – Fundamental Principles

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface …

specific surface - calculator.org

Specific surface is important for the design of chemical processes that involve surface reactions. For example, the material used to provide a catalyst bed needs to have a large surface area. Specific surface is difficult to measure directly, but can often be calculated from knowledge of the surface structure and making reasonable approximations.

Midship, frontal surface area and flotation

frontal surface area is the projected area, along the path of the fluid, to a plane perpendicular to the direction of motion. it is the area that presents the object to the fluid path. We call this area the "Midship" of the ship. The higher this area is, the greater the drag force is.. Naval architects use the value "Midship section coefficient" (Cm) to express the slenderness of the ship's ...
