Allin A thesis submitted in partial fulfillment of the requirements for the degree of Masters in Geoscience: Geology Option Montana Technological University 2019 ii Abstract Experiments were conducted to determine the relative rates of reduction of aqueous sulfate and aqueous arsenite (As(OH)3,aq) using foils of copper, nickel, or cobalt as the reductant, at temperatures of 150ºC to 300ºC. At the highest temperature of 300°C, very limited sulfate reduction was observed with cobalt foil, but sulfate was reduced to sulfide by copper foil (precipitation of Cu2S (chalcocite)) and partly reduced by nickel foil (precipitation of NiS2 (vaesite) + NiSO4·xH2O). In the 300ºC arsenite reduction experiments, Cu3As (domeykite), Ni5As2, or CoAs (langisite) formed. In experiments where both sulfate and arsenite were present, some produced minerals were sulfarsenides, which contained both sulfide and arsenide, i.e. cobaltite (CoAsS). These experiments also produced large (~10 µm along longest axis) euhedral crystals of metal-sulfide that were either imbedded or grown upon a matrix of fine-grained metal-arsenides, or, in the case of cobalt, metal-sulfarsenide. Some experimental results did not show clear mineral formation, but instead demonstrated metal-arsenic alloying at the foil edges. -

Geochemistry, Mineralogy and Microbiology of Cobalt in Mining-Affected Environments
minerals Article Geochemistry, Mineralogy and Microbiology of Cobalt in Mining-Affected Environments Gabriel Ziwa 1,2,*, Rich Crane 1,2 and Karen A. Hudson-Edwards 1,2 1 Environment and Sustainability Institute, University of Exeter, Penryn TR10 9FE, UK; [email protected] (R.C.); [email protected] (K.A.H.-E.) 2 Camborne School of Mines, University of Exeter, Penryn TR10 9FE, UK * Correspondence: [email protected] Abstract: Cobalt is recognised by the European Commission as a “Critical Raw Material” due to its irreplaceable functionality in many types of modern technology, combined with its current high-risk status associated with its supply. Despite such importance, there remain major knowledge gaps with regard to the geochemistry, mineralogy, and microbiology of cobalt-bearing environments, particu- larly those associated with ore deposits and subsequent mining operations. In such environments, high concentrations of Co (up to 34,400 mg/L in mine water, 14,165 mg/kg in tailings, 21,134 mg/kg in soils, and 18,434 mg/kg in stream sediments) have been documented. Co is contained in ore and mine waste in a wide variety of primary (e.g., cobaltite, carrolite, and erythrite) and secondary (e.g., erythrite, heterogenite) minerals. When exposed to low pH conditions, a number of such minerals are 2+ known to undergo dissolution, typically forming Co (aq). At circumneutral pH, such aqueous Co can then become immobilised by co-precipitation and/or sorption onto Fe and Mn(oxyhydr)oxides. This paper brings together contemporary knowledge on such Co cycling across different mining environments. -

Om Group, Inc. 2002 Annual Report Dear Fellow Shareowners
OM GROUP, INC. 2002 ANNUAL REPORT DEAR FELLOW SHAREOWNERS: In 2002, OM Group confronted the most challenging conditions in its history. An increasingly weak global economy, a depressed cobalt price and various operating issues associated with our nickel business all combined to limit earnings and cash flow from our Base Metals business. As a result, our ability to reduce the significant amount of incremental debt associated with the acquisition of the Precious Metals business in late 2001 was severely impaired in the near term. We met these challenges by developing and launching an aggressive and broad-based corporate restructuring plan designed to increase profitability, reduce costs, quickly restore our balance sheet strength and reposition OMG for future growth. The key components of our plan include: ( Generating up to $100 million from the sale of non-core assets, including the SCM Powdered Metals business; Tungsten Carbide technology and related assets; and the PVC Heat Stabilizer and other assets, such as the Microbond product lines; ( Reducing workforce expenses by approximately $35 million in 2003, and by approximately $45 million on an annualized basis starting in 2004, through the elimination of approximately 550 positions; ( Lowering other manufacturing and administrative costs by approximately $30 million in 2003, and by approximately $40 million on an annualized basis starting in 2004; and ( Initiating the process to monetize some portion or all of our Precious Metals Businesses through either a strategic or financial partnership. With this blueprint in hand, the company successfully amended its senior credit facilities. Completing this step provided the access to the capital and liquidity necessary to fully implement our restructuring initiatives which, in the fourth quarter, resulted in restructuring and other charges of approximately $330 million. -

THE CHARACTERIZATION OF ARSENIC MINERAL PHASES FROM LEGACY MINE WASTE AND SOIL NEAR COBALT, ONTARIO by Jeff Clarke A research project submitted to the Department of Geological Sciences and Geological Engineering In conformity with the requirements for the degree of Master of Science in Applied Geology Queen’s University Kingston, Ontario, Canada (July, 2017) Copyright © Jeff Clarke, 2017 i ABSTRACT The Cobalt-Coleman silver (Ag) mining camp has a long history of mining dating back to 1903. Silver mineralization is hosted within carbonate veins and occurs in association with Fe-Co-Ni arsenide and sulpharsenide mineral species. The complex mineralogy presented challenges to early mineral processing methods with varying success of Ag recovery and a significant amount of arsenic (As) in waste material which was disposed in the numerous tailings deposits scattered throughout the mining camp, and in many instances disposed of uncontained. The oxidation and dissolution of As-bearing mineral phases in these tailings and legacy waste sites releases As into the local aquatic environment. Determining the distribution of primary and secondary As mineral species in different legacy mine waste materials provides an understanding of the stability of As. Few studies have included detailed advanced mineralogical characterization of As mineral species from legacy mine waste in the Cobalt area. As part of this study, a total of 28 samples were collected from tailings, processed material near mill sites and soils from the legacy Nipissing and Cart Lake mining sites. The samples were analyzed for bulk chemistry to delineate material with strongly elevated As returned from all sample sites. This sampling returned highly elevated As with up to 6.01% As from samples near mill sites, 1.71% As from tailings and 0.10% As from soils. -

Spatial distribution of the ophiolite-hosted Co–Ni–As-rich hydrothermal mineralization in the Punta Corna Mining complex, Lanzo Valleys, Northern Italy Giovanni Grieco1, Marilena Moroni1, Micol Bussolesi2, Alessandro Cavallo2, and Simone Orizio1 1Earth Science Department, University of Milan, via S. Botticelli 23, 20133, Milan, Italy 2Department of Earth and Environmental Sciences – DISAT, University of Milan-Bicocca, p.zza della Scienza 1–4, 2016 Milan, Italy Cobalt is a transition metal with a trace element abundance in the Earth’s crust (26.6 ppm). It forms mainly sulfides like carrollite, siegenite and linneite and enters the cobaltite-gersdorffite solid solution and di-tri-arsenides safflorite, rammelsbergite and skutterudite while erythrite and asbolane are secondary Co phases. Cobalt is a Critical Raw Material for the EU, strategically important due to its use in the industry (batteries, superalloys, catalysts etc.). Italy hosts several Co-bearing hydrothermal deposits, which were variably exploited in the past. In this work we focus on the Co-Fe-Ni hydrothermal veins emplaced within the metabasites of the Lanzo Valleys ophiolite complex in the western sector of the Alpine belt. The vein system is collectively called “Punta Corna mining complex”, and was exploited for Fe, Ag and later Co in the past (Castelli et al., 2011, Moroni et al., 2019). A detailed field survey of the past cobalt mining works was carried out in summer 2019, followed by sampling, mostly inside mining tunnels and from waste dumps in order to increase data about this poorly known vein system.
