Distribution of As, Ni and Co in Tailings and Surface Waters in the Cobalt Area, Ontario1
DISTRIBUTION OF AS, NI AND CO IN TAILINGS AND SURFACE 1 WATERS IN THE COBALT AREA, ONTARIO Jeanne B. Percival2, Y.T. John Kwong3, Charles G. Dumaresq4, Frederick A. Michel5 Abstract: From 1904 until the mid 1930’s and intermittently until 1989, over 450 million troy ounces of silver was mined from the Cobalt area, Ontario. Currently there is no active mining of silver, but the area has seen recent exploration activities for other commodities such as diamonds. Cobalt, however, has not only a renowned mining history, but also an environmental legacy. The area is characterized by remnant historic mine workings and numerous waste rock piles and tailings ponds. Several elements of concern including arsenic, nickel and cobalt continually enter the local watershed from the tailings and waste rock piles. These elements are transported through surface waters to the wetlands in the Farr Creek drainage basin and ultimately enter Lake Timiskaming. Tailings samples are composed of abundant plagioclase with subordinate quartz, chlorite, calcite and dolomite. Less common are K-feldspar, amphibole and mica as well as trace minerals such as erythrite, scorodite and pharmocolite. When efflorescent mineral crusts form on tailings surfaces they are dominated by either gypsum or thenardite. The tailings may contain up to 3.5 wt % Co and 2.2 wt% Ni. Lake sediment and tailings cores show concentrations up to 1.8 wt% As, 0.62 wt% Co and 0.27 wt% Ni in the solids, and 160 mg/L As, 74 mg/L Co and 42 mg/L Ni in the pore waters. One core collected from the infilled Hebert Pond situated within the Nipissing Low Grade Mill tailings impoundment show pore water concentrations in excess of 1,500 mg/L As associated with an organic- rich layer. -

ABSTRACT A multidisciplinary approach has been applied to four subeconomic deposits of platinum metals in order to propose a new model of formation for platinum group element (PGE) deposits devoid of significant base metal sulphides (BMS). The aim was to facilitate the identification of new targets for PGE exploration. Two of the deposits occur in Albania, in the Tropoja and Bulqiza massifs respectively; these belong to an ophiolitic belt created in an oceanic environment during the Upper Jurassic. -

Origin of Platinum Group Minerals (PGM) Inclusions in Chromite Deposits of the Urals
minerals Article Origin of Platinum Group Minerals (PGM) Inclusions in Chromite Deposits of the Urals Federica Zaccarini 1,*, Giorgio Garuti 1, Evgeny Pushkarev 2 and Oskar Thalhammer 1 1 Department of Applied Geosciences and Geophysics, University of Leoben, Peter Tunner Str.5, A 8700 Leoben, Austria; [email protected] (G.G.); [email protected] (O.T.) 2 Institute of Geology and Geochemistry, Ural Branch of the Russian Academy of Science, Str. Pochtovy per. 7, 620151 Ekaterinburg, Russia; [email protected] * Correspondence: [email protected]; Tel.: +43-3842-402-6218 Received: 13 August 2018; Accepted: 28 August 2018; Published: 31 August 2018 Abstract: This paper reviews a database of about 1500 published and 1000 unpublished microprobe analyses of platinum-group minerals (PGM) from chromite deposits associated with ophiolites and Alaskan-type complexes of the Urals. Composition, texture, and paragenesis of unaltered PGM enclosed in fresh chromitite of the ophiolites indicate that the PGM formed by a sequence of crystallization events before, during, and probably after primary chromite precipitation. The most important controlling factors are sulfur fugacity and temperature. Laurite and Os–Ir–Ru alloys are pristine liquidus phases crystallized at high temperature and low sulfur fugacity: they were trapped in the chromite as solid particles. Oxygen thermobarometry supports that several chromitites underwent compositional equilibration down to 700 ◦C involving increase of the Fe3/Fe2 ratio. These chromitites contain a great number of PGM including—besides laurite and alloys—erlichmanite, Ir–Ni–sulfides, and Ir–Ru sulfarsenides formed by increasing sulfur fugacity. Correlation with chromite composition suggests that the latest stage of PGM crystallization might have occurred in the subsolidus. -

Samples collected on ore and waste dumps were used to identify and characterize the previously uninvestigated suite of supergene mineral phases by standard mineralogical techniques. The following species were determined (in alphabetical order): annaber- gite, arseniosiderite(?), gypsum, hexahydrite, hörnesite, pararealgar, roméite-group minerals, rozenite, scorodite, sen- armontite, stibiconite, sulphur, tripuhyite and valentinite. Their occurrences are described and their local conditions of formation are discussed. High-resolution Raman spectra of hörnesite, hexahydrite and rozenite are provided and com- pared with literature data.
