Coal Preparation Flowsheet Signal Flowgraph

Simulation of multi-stage gravity separation circuits by size–density bivariate partition function

“…In latter context, the staged separation processes have been studied by a variety of techniques including circuit enumeration, signal flowgraph, nodal mass balance and combinatorics. The analyses are generally restricted to particle-particle separation by either size or density, that is, in terms of partition functions in a single attribute (Austin et al, 1984;Salama and Mikhail, 1985;Rao et al, 1986;Meloy et al, 1986;Ferrara et al, 1986;Klima and Luckie, 1986;Heiskanen, 1993;Luckie, 2003).…”

The effect of feed overload at secondary coal separation with product recirculation

“…Also for the coal flotation it is possible to obtain better beneficiation results by appropriate configuration and recirculation of the flotation products [6]. However, there are very few studies on coal gravity separation with product recirculation [9,12,15,17,18]. Improved washing efficiency can be expressed by less erroneous grains in the concentrate and the waste [10].…”
