ABSTRACT: Factors affecting floatation of fish ball in water were investigated. The density of threadfin bream (TB) surimi paste significantly decreased (P < 0.05) as moisture content, temperature, or salt concentration increased.The ability of surimi paste to float or sink in water was observed according to changes in density.

There are many factors affecting the flotation process, including non-adjustable factors and adjustable factors.Among them, non-adjustable factors refer to the ore property, adjustable factors mainly include grinding fineness, pulp concentration, pulp pH value, reagent system, pulp temperature, water quality, flotation time and so on.

Affecting factors of hematite flotation are mineral particle size, pulp concentration, flotation reagent system, design of flotation separation process and other. Minerals size, through crushing and grinding operations, on the one hand, to make useful mineral ore monomer dissociation, and on the other hand to provide suitable grain size of raw ...

Sinking and floating has to do with density, which is the mass (how heavy it is) of the object over the volume (the amount of space it takes up). Water has a density of exactly one, which means ...

Factors Affecting Buoyancy Force. Factors affecting buoyancy force refer to the elements or conditions that may alter the magnitude of pressure exerted on an object that is immersed in a fluid, wholly or partly. Discovered by Greek Philosopher, Archimedes, Buoyancy force occurs as a result of the differences in pressure acting on opposite sides of an object that is immersed in a stagnant fluid.

The flotation of fine molybdenite particles (minus 200 mesh) is sensitive to particle size and heterocoagulation. Results of tests conducted to assess the effects of overgrinding of molybdenite have indicated that while there is no change in the crystal structure due to prolonged grinding, the floatability is significantly reduced due to the ...

Capital structure is important in several ways. First, it determines which part of company’s assets is funded by shareholders and which is attributable to lenders. Second, capital structure affects company’s solvency – key financial ratios like Debt / EBITDA and Debt / Equity are dependent on capital structure. Factors affecting capital structure decision of a firm are therefore critical ...
