Miller, Jan D. | Agglomeration and magnetic deinking for office paper | Magnet deinking of office paper (OP) is a promising technology for the production of high quality secondary fiber. The technique is possible because a significant portion of the toner in OP furnish has a magnetic character. Toner magnetic susceptibility can vary from weakly paramagnetic to ferroma... | Wastepaper; Magnetic deinking; Toner; Magnetic susceptibility | 2000 |

Zhdanov, Michael S. | Electromagnetic inversion using quasi-linear approximation | Three-dimensional electromagnetic inversion continues to be a challenging problem in electrical exploration. We have recently developed a new approach to the solution of this problem based on quasi-linear approximation of a forward modeling operator. It generates a linear equation with respect to ... | Quasi-linear approximation; Electromagnetic inversion | 2000 |

Miller, Jan D. | Evaluation of plantwide control strategies for coal preparation plants | The quality of cleaned products from coal preparation plants is often variable due to natural fluctuations in the washability characteristics of the plant feed. To combat this problem, many modern plants have installed on-line analyzers that provide feedback for the real-time control of product q... | Circuit; Yield; Optimization | 2000 |

Miller, Jan D. | Interaction forces between toner surfaces | The interaction of toner particles in aqueous solution is of interest with regard to both fundamental and practical aspects of de-inking processes. It has been established for the toner studied that the toner polymeric resin, that is, the block copolymer styrene-methyl methacrylate, more specifical... | Interaction forces; toner surfaces; PMMA | 2000 |

Miller, Jan D. | Noncyanide leaching of an auriferous pyrite ore from Ecuador | Gold leaching of an auriferous pyrite ore from the Portovelo deposit in Ecuador indicates that noncyanide leaching systems, such as thiocyanate and thiourea, are not as effective as the traditional cyanide system. For example, whereas approximately 95% of the gold can be leached from the ore with cy... | Gold leaching; Refractory ores; Thiocyanate; Thiourea | 2000 |

Zhdanov, Michael S. | Quasi-analytical approximation and series in electromagnetic modeling | The quasi-linear approximation for electromagnetic forward modeling is based on the assumption that the anomalous electrical field within an inhomogeneous domain is linearly proportional to the background (normal) field through an electrical reflectivity tensor ˆλ. In the original formulation of... | Electromagnetic modeling; Quasi-linear approximation; Quasi-analytical approximation; Quasi-analytical series | 2000 |
