Photochemical Changes in Cyanide Speciation in Drainage from a Precious Metal Ore Heap

Autor: Reinhard W. Leinz, Craig A. Johnson, Robert O. Rye, David J. Grimes

Publikováno v: Environmental Science & Technology. 36:840-845

In drainage from an inactive ore heap at a former gold mine, the speciation of cyanide and the concentrations of several metals were found to follow diurnal cycles. Concentrations of the hexacyanoferrate complex, iron, manganese, and ammonium were hi

Anomalous gold, antimony, arsenic, and tungsten in ground water and alluvium around disseminated gold deposits along the Getchell Trend, Humboldt County, Nevada

Autor: Allen L. Meier, David J. Grimes, Walter H. Ficklin, John B. McHugh

Publikováno v: Journal of Geochemical Exploration. 52:351-371

Ground-water, alluvium, and bedrock samples were collected from drill holes near the Chimney Creek, Preble, Summer Camp, and Rabbit Creek disseminated gold deposits in northern Nevada to determine if Au and ore-related metals, such as As, Sb, and W,

Cyanide speciation at four gold leach operations undergoing remediation

Autor: Reinhard W. Leinz, David J. Grimes, Craig A. Johnson, Robert O. Rye

Publikováno v: Environmental sciencetechnology. 42(4)

Analyses have been made of 81 effluents from four gold leach operations in various stages of remediation to identify the most -persistent cyanide species. Total cyanide and weak acid-dissociable (WAD) cyanide were measured using improved methods, and

Publikováno v: Drug Safety. 5:447-454

An 18-year-old female patient receiving adjuvant chemotherapy for osteogenic sarcoma developed a pruritic erythematous rash during infusion of the eighth dose of methotrexate (8 g/m2) in the series. In other respects, the infusion proceeded normally

Accounting for cyanide and its degradation products at three Nevada gold mines; constraints from stable C- and N-isotopes

Autor: David J. Grimes, Robert O. Rye, Craig A. Johnson

Publikováno v: Open-File Report.

An understanding of the fate of cyanide (CN) in mine process waters is important for addressing environmental concerns and for taking steps to minimize reagent costs. The utility of stable isotope methods in identifying cyanide loss pathways has been
