Miller, Jan D. | The behavior of arsenic trioxide in non-ferrous extractive metallurgical processing | Study of the acid bake-leach process has shown potential advantages for the treatment of enargite (Cu3AsS4) concentrates. Among the most important advantages of the process is the transformation of enargite to water-soluble copper sulfate and highly soluble arsenic trioxide (arsenolite). Because ars... | 2014-01-01 | |

Miller, Jan D. | Effect of surface oxidation on interfacial water structure at the pyrite (100) surface as studied by MDS | Flotation provides a number of alternatives for the processing of gold ores containing sulfide minerals. e.g. flotation of free gold and gold-bearing sulfides to produce a gold-rich concentrate for regrinding, oxidative pretreatment and cyanidation. | 2014-01-01 | |

Solomon, Douglas Kip | Evaluating the use of strontium isotopes in tree rings to record the isotopic signal of dust deposited on the Wasatch Mountains | Dust cycling from the Great Basin to the Rocky Mountains is an important component of ecological and hydrological processes. We investigated the use of strontium (Sr) concentrations and isotope ratios (87Sr/86Sr) in tree rings as a proxy for dust deposition. We report Sr concentrations and isotope r... | 2014-01-01 | |

Steenburgh, William James | Finescale orographic precipitation variability and gap-filling radar potential in Little Cottonwood Canyon, Utah | Finescale variations in orographic precipitation pose a major challenge for weather prediction, winter road maintenance, and avalanche forecasting and mitigation in mountainous regions. In this investigation, ground based X-band radar observations collected during intensive observing period 6 (IOP6)... | 2014-01-01 | |

Miller, Jan D. | Flotation chemistry of soluble salt minerals: from ion hydration to colloid adsorption | In this paper, recent progress with respect to the flotation chemistry of soluble salt minerals is reviewed, and some of the more relevant issues including the hydration states of ions, the interfacial phenomena of salt surfaces and the flotation behavior of selected soluble salts are discussed. Due... | 2014-01-01 | |

Garrett, Timothy J. | Observed influence of riming, temperature, and turbulence on the fallspeed of solid precipitation | Forecasts of the amount and geographic distribution of snow are highly sensitive to a model's parameterization of hydrometeor fallspeed. Riming is generally thought to lead to particles with a higher mass and terminal velocity. Yet models commonly assume that heavily rimed particles such as graupel ... | 2014-01-01 | |

Solomon, Douglas Kip | Tracer applications of noble gas radionuclides in the geosciences | Noble gas radionuclides, including 81Kr (t1/2 = 229,000 yr), 85Kr (t1/2 = 10.8 yr), and 39Ar (t1/2 = 269 yr), possess nearly ideal chemical and physical properties for studies of earth and environmental processes. Recent advances in Atom Trap Trace Analysis (ATTA), a laser-based atom counting method... | 2014-01-01 | |

Miller, Jan D. | Understanding the agglomeration behavior of nickel laterite and gold ores using statistical design of experiments | The drum agglomeration of nickel laterite and gold ores has been optimized through the design of experiments (DOE) using a Taguchi L16 (45) orthogonal array to determine the optimum conditions for maximizing average agglomerate size and minimizing the amount of fines. The effects of controllable ope... | 2014-01-01 |
