Miller, Jan D.; Lin, Chen-Luh | 3D analysis of particulates in mineral processing systems by cone beam X-ray microtomography | In general, x-ray computed tomographic (CT) techniques are able to provide 3D images of the internal structure of opaque materials in a nondestructive manner. The unique cone beam geometry allows acquisition of all 2D projections with only one rotation of the sample thus providing for fast data acqu... | X-ray microtomography; Liberation; Heap leaching; Exposure analysis; Coal washability | 2003 |

Miller, Jan D.; Fang, Zhigang Zak; Lin, Chen-Luh | Characterization of powder injection molded components using X-ray CT | A good understanding of the microstructure of powder injection molded (PIM) components during debinding and sintering is essential in designing and optimizing PIM processes and properties. So far we have been limited in our ability to "see" what is going on. Microstructural characterization has cla... | Powder injection molding | 2003 |

Miller, Jan D. | Characterization of spherical alumina particles obtained by melting in a hydrogen-oxygen flame | Spherical oxide particles can be used as mineral fillers, paint pigments, polishing materials and catalysts. They can be prepared using various techniques involving precipitation and spray drying. Melting of particles in a high-temperature flame is a simple technique which produces particles with ... | Alumina; Oxides; Hydrogen-oxygen flame | 2003 |

Miller, Jan D. | Influence of surfactants on interaction forces between polyethylene surfaces in a hydrocarbon solvent | The polyolefins, mainly polyethylene and polypropylene particles, are used as an active filler material in polymer-polymer blends and are being used for the modification of asphalts to provide for high-load, low-maintenance road construction. The stability of prepared blends depends on the interact... | Surfactants; Asphalt; Polymer; Polyolefins | 2003 |

Miller, Jan D.; Nalaskowski, Jakub | Interaction forces between silica surfaces in aqueous solutions of poly(ethylene oxide)s | An understanding of forces responsible for the stability of dispersions of colloidal particles when interacting with each other in aqueous solutions is of great interest academically and industrially. When water-soluble polymers are adsorbed onto colloidal particles, various effects on the stabil... | Water-soluble polymers; Colloidal particles; Interaction forces | 2003 |

Miller, Jan D.; Lin, Chen-Luh | Particle size distribution for copper heap leaching operations as established from 3D mineral exposure analysis by X-ray microCT | The particle size distribution (PSD) for copper heap leaching is an important consideration in the design and operation of any copper heap leaching facility. High-resolution 3D X-ray microtomography (XMT) can be used for the direct determination of the percentage of exposed valuable mineral grains i... | Particle size distribution; Leaching; X-ray microtomography | 2003 |

Miller, Jan D. | Surfactant adsorption density calculation from Fourier transform infrared external reflection spectroscopy (FTIR/ERS) | An equation to calculate surfactant adsorption density from Fourier transform infrared external reflection spectra was established. The derivation and limitation of this equation are discussed in detail. The validation of the FTIR/ERS adsorption density equation was experimentally verified from t... | Surfactant; Adsorption density; Solid film | 2003 |

Miller, Jan D. | Thiocarbonate collectors in pyrite flotation ? fundamentals and applications | Recent results from electrochemical measurements demonstrate that trithiocarbonate (TTC) collectors are more readily oxidized to their corresponding dithiolates than the dithiocarbonate/xanthate (DTC) collectors. Based on the traditional analysis of collector adsorption, trithiocarbonates might then... | Trithiocarbonate; xanthate; nitrogen | 2003 |
