Miller, Jan D. | Dispersed oil impact on froth stability in flotation | Foam stability in flotation has been studied for more than half of the last century, however, the mechanisms responsible for the defoaming action of many presently used reagents are not completely understood. This research presents oil flotation data, which may be used in the evaluation of aqueous ... | Particles; Defoaming; Surfactants | 2001 |

Golden, Kenneth M. | Exact result for the effective conductivity of a continuum percolation model | A random two-dimensional checkerboard of squares of conductivities 1 and 8 in proportions p and 1 - p is considered. Classical duality implies that the effective conductivity obeys o* = V8 at p = 1/2. It is rigorously found here that to leading order as 8--0, this exact result holds for all p in the... | Particles; Matrix; Checkerboard | 1994 |

Miller, Jan D. | Experimental evaluation of a mineral exposure model for crushed copper ores | Copper mineral inclusions dispersed in crushed ore particles have a certain size distribution (grain-size distribution). For efficient heap leaching processes, the crushing plant should be designed and operated to crush the ore to an appropriate particle-size distribution so that copper mineral grai... | Grains; Particles; Distribution | 2006 |

Miller, Jan D. | Particle size segregation on a belt conveyor | Particle size segregation is a common phenomenon in many particulate processes and has many undesirable effects. The size segregation which occurs on a belt conveyor causes a serious problem for on-line particle size measurement using image-based techniques. Whether particle size distributions mea... | Particles; Size; Belt conveyors; Modelling | 1997 |

Miller, Jan D. | Toner ink particle morphology in air-sparged hydrocyclone flotation deinking | A series of pulping and flotation deinking tests were performed using a pilot-scale air-sparged hydrocyclone (ASH) flotation cell and a toner ink printed furnish. Microscopy studies indicate ink particles in both the flotation accepts and rejects are relatively flat. Many of the ink particles ap... | Elongation; Cyclone; Particles | 1996 |
