Resumo

WOOLLACOTT, L.C.; BWALYA, M.  e  MABOKELA, L.. A validation study of the King stratification model. J. S. Afr. Inst. Min. Metall. [online]. 2015, vol.115, n.2, pp. 93-101. ISSN 2411-9717.

This paper presents a study on the ability of the King stratification model to describe density stratification patterns that are achieved under idealized conditions. Tests were conducted in a batch jig using artificial particles in seven density classes. All particles in a density class had essentially the same density, size, and shape. Tests were conducted for particle systems involving from two to seven components. Good agreement was obtained between measured and modelled data to an extent that gave strong endorsement of the mathematical appropriateness of the core equation in the King model. Somewhat ambiguous results were found with regard to claims about the independencies of the single experimentally-determined parameter required by the model.
