Stability of sodium polyphosphate dispersants in mineral ...

Dec 01, 2012  1. Introduction. Dispersion is a key component in a wide range of mineral and material processing applications. In mineral processing, dispersants are commonly used to reduce or even eliminate aggregation, by control of slurry viscosity, during pumping to enable efficient transportation of high pulp solid loadings (Kapur et al., 1997).Dispersants are used to aid in suspending solids in a ...

Dispersion of fine mineral particles in water - ScienceDirect

Jan 01, 1992  The separation of fine mineral particlesmay be completely unselective if a predispersion stage is absent or unefficient. Good dispersion isalso important for classification as well as for other fine particle processing. The aim of our research is to explore why dispersion is necessary for fine particle processing and how to achieve a good ...

Particle-size distribution - Wikipedia

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
