Miller, Jan D. | Axial flow reversal and its significance in air-sparged hydrocyclone (ASH) flotation | In recent years the potential of air-sparged hydrocyclone (ASH) flotation for fine coal cleaning has been demonstrated both in pilot plant testing and in a plant-site demonstration program. Further improvements in the ASH technology will depend, to some extent, on improved understanding of the co... | Flotation; zero axial velocity; computational fluid dynamics | 1995 |

Miller, Jan D. | Characterization of interfacial water at hydrophilic and hydrophobic surfaces by in situ FTIR/internal reflection spectroscopy | In-situ FTIR/internal reflection spectroscopy (FTIR/IRS) has been used to spectroscopically characterize interfacial water near hydrophilic (silicon single crystal) and hydrophobic (polymer-coated germanium single crystal) surfaces. Interfacial water was examined spectroscopically over certain dista... | Interfacial water; hydrophilic surfaces; Hydrophobic surfaces; Internal reflection spectroscopy; Silicon crystals; Germanium crystals | 1995 |

Miller, Jan D. | Critical review of wetting and adhesion phenomena in the preparation of polymer-mineral composites | The wetting behavior of liquid polymers at solid surfaces and the adhesion forces involved at polymer-filler interfaces should always be considered in the preparation of high-quality polymer composites, including those made with mineral fillers. Spontaneous polymer spreading over the filler surface... | Polymer-minerals; Composites; Wetting; Adhesion | 1995 |

Miller, Jan D. | Flow phenomena and its impact on air-sparged hydrocyclone flotation of quartz | Fluid flow phenomena and therefore the flotation efficiency of air-sparged hydrocyclone (ASH) flotation are strongly dependent on operating and design variables such as air and slurry flow rates, underflow and overflow opening areas, percent solids of the feed, reagent levels, particle size and ASH... | Quartz; Flotation; Hydrocyclones | 1995 |

Miller, Jan D. | Microscopic observations of bitumen spreading at gas bubble surfaces | Bitumen spreading at gas bubble surfaces was observed through a stereoscopic microscope for Whiterocks oil sand samples submerged in alkaline solutions. This phenomenon was also observed for model systems where air bubbles were placed al the surface of bitumen-coated quartz slide. Finally, the film ... | Hydrophobic minerals; Oil sand; Gas bubbles | 1995 |

Miller, Jan D.; Lin, Chen-Luh | On-line washability analysis for the control of coarse coal cleaning circuits | In view of the success of recent laboratory studies using X-ray computed tomography (CT) to determine coal washability and with the availability of high-speed CT systems, it now seems possible to design an on-stream washability system for the control of coarse coal-cleaning circuits. Design features... | On-stream washability; CT analyzer; Coal washability | 1995 |

Zhdanov, Michael | Resistivity imaging by time domain electromagnetic migration (TDEMM) | One of the most challenging problems of electrical geophysical methods is the interpretation of time domain electromagnetic (TDEM) sounding data in the areas with the horizontally inhomogeneous geoelectrical structures. This problem is of utmost importance in mining exploration and environmental stu... | 1995 | |

Miller, Jan D. | Thermogravimetric/Mass spectrometric (TG/MS) characterization of toner particles from photocopied wastepaper and the impact of these features on flotation deinking | Flotation deinking of photocopies from office waste is known to be much more difficult than the flotation deinking of newsprint. In this regard, research has been undertaken to better understand the phenomena which account for the poor efficiency in the flotation deinking of such office waste. Durin... | Photocopied paper; Recycling; Deinking; Flotation; Thermal decomposition; Thermogravimetry; Mass spectrometry; Differential scanning calorimeter; Toner particles | 1995 |
