Jewell, Paul | Controls of tufa development in Pleistocene Lake Bonneville, Utah | Prominent tufa localities along the Provo level (∼14,000 14C yr B.P.) shoreline in Pleistocene Lake Bonneville have been characterized in detail. Three types of tufa are recognized: capping tufa, beachrock, and capping tufa over beachrock. Capping tufa and beachrock are end members of a continuum ... | Tufa; Pleistocene; Pluvial lakes | 2006 |

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. | Integral electric current method in 3-D electromagnetic modeling for large conductivity contrast | Abstract-We introduce a new approach to 3-D electromagnetic (EM) modeling for models with large conductivity contrast. It is based on the equations for integral current within the cells of the discretization grid, instead of the electric field or electric current themselves, which are used in the c... | Electromagnetic modeling; Integral electric current method; 3-D modeling; High conductivity contrast; Integral equations | 2007-05 |

Miller, Jan D. | Hydroxamate vs. fatty acid flotation of iron oxide | Data were obtained with hematite with octyl hydroxamate and oleate as collectors to determine the mechanism of collector adsorption and also to establish the roles that conditioning time and temperature assume in this system. The presence of hydroxy complexes of iron are apparently necessary for che... | Iron ore; Iron; Fatty acid; Hydroxy complexes | 1970 |

Reichler, Thomas J. | Expansion of the Hadley cell under global warming | A consistent weakening and poleward expansion of the Hadley circulation is diagnosed in the climate change simulations of the IPCC AR4 project. Associated with this widening is a poleward expansion of the subtropical dry zone. Simple scaling analysis supports the notion that the poleward extent of ... | Hadley cell; Climate change; Subtropical dry zone | 2007 |

Miller, Jan D. | Hydrometallurgy | The science and technology of hydrometallurgy and chemical processing continues to advance both at the laboratory level and in plant practice. In past decades, hydrometallurgy was rather limited in scope and received relatively little attention, being largely a laboratory curiosity.

Miller, Jan D. | Analysis of the surface potential developed by non-reactive ionic solids | The sign of the surface potential for complex non-reactive ionic solids cannot be predicted solely from consideration of the hydration energy of gaseous ions which constitute the ionic lattice. Accurate analysis of these systems must involve the hydration energy of surface ions, which requires knowl... | Lattice; dipole; Madelung Constants | 1976 |

Miller, Jan D. | Chemical utilization of sequestered carbon dioxide as a booster of hydrogen economy | For many, hydrogen in a pure hydrogen economy would be like natural gas in today's energy economy. Unfortunately, hydrogen's physical properties are unsuited to the energy market's requirements in terms of packaging, storage, transfer, and delivery. In this paper, a hybrid energy economy that packag... | | 2008-01-01 |

Jewell, Paul | Paleoredox conditions and the origin of bedded barites along the Late Devonian North American continental margin | The most important controls of the redox state of natural waters are the flux of organic matter from the photic zone, the degree of physical mixing, and oxygen concentrations of any connecting water masses. In coastal upwelling zones, these factors can be described with a simple box model constraine... | Bedded barites; Late Devonian; Continental margin; Redox state | 1994 |
