Miller, Jan D. | Direct three-dimensional liberation analysis by cone beam x-ray microtomography | Liberation of valuable minerals during size reduction is an important aspect of mineral processing technology. In practice, most quantitative information on liberation is based on the application of stereological theorems for the analysis of image data from two-dimensional polished sections. On th... | Mineral processing; Cone beam x-ray; Microtomography | 1997 |

Miller, Jan D. | Effect of ink types and printing processes on flotation deinking | Examination of ink types reveals that newsprint oil-based offset-cold and offset-heat inks contain substantial oil (45 to 60%) and resin (5 to 35%), water-based ink contains water (40%) and resin (polystyrene, 30%). These inks are liquids with densities around 1 g/cm3, having various viscosities... | Toners; Inks; Photocopying; Laser printing; Flotation; Deinking; Recycling; Office waste; Hyrdophobicity | 1997 |

Miller, Jan D. | Magnetic separation for wastepaper recycle mills | An alternative approach to the conventional washing and flotation techniques for de-inking of mixed office waste (MOW) is magnetic separation. The use of magnetic de-inking has great potential to improve the efficiency of ink removal due to the magnetic content of toners. It is shown experimen... | Deinking; Paper pulp; Wastepaper; Magnetic separation | 1997 |

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. | Removal of volatile organic compounds from contaminated water using air-sparged hydrocyclone stripping technology | The air-sparged hydrocyclone (ASH) technology offers the unique opportunity to achieve efficient removal of volatile organic compounds (VOCs) from contaminated water at a high specific capacity, more than 100 times that of conventional air stripping technologies. VOC stripping is the first applicati... | Air-sparged hydrocyclone; Air stripping; Contaminated water | 1997 |

Miller, Jan D. | Surface chemistry of pulping and flotation for mixed office wastepaper | The effect of pulping reagents on the de-inking flotation of laser printed wastepaper was investigated with regard to the removal efficiency of toner and mineral filler particles at different pH values. These results show that caustic pulping causes the toner to be released from the fibers as larg... | Pulping reagents; Deinking; Toner; Mineral fillers | 1997 |
