...RALPH JEROME HOLMES Abstract X-ray, microscopic, microchemical, contact-print, and mineral synthesis techniques have been applied to the problem of the relationships of the higher natural arsenides of cobalt, nickel, and iron. The data obtained have been correlated with a review of existing...

..., cobalt pentlandite, heazlewoodite, and awaruite. The peridotite also contains two Ni-arsenide minerals, orcélite and maucherite; and, less commonly, the sulfides pyrrhotite, bismuthinite, bornite, and parkerite(?). These minerals form tiny to small (~3–100 μm) grains sparsely scattered amongst...

... are not available for the cobalt arsenide and sulfarsenide minerals that form the vein-type ore deposits, we use chemographic analysis to qualitatively evaluate their stability relationships and predict the physicochemical controls of ore formation. The data and interpretations of processes presented in this paper...

... in the mineralization. Textural relationships suggest a depositional sequence proceeding from Ni monoarsenide (nickeline) to Ni-Co-Fe di-arsenides (rammelsbergite, Ni-Co diarsenides, Co-Fe di-arsenides) to cobalt triarsenide (skutterudite) reflecting progressive increase in Co and As concentrations (see Fig. 5A...

... and cementation of the fragments by arsenides, sulfarsenides, and sulfides. The main cobalt ore minerals are skutterudite, safflorite, and cobaltite ( Table 1 ), which are accompanied by variable proportions of ankerite and dolomite. In most deposits, skutterudite was the first mineral to crystallize, followed...

... piles. Additionally, arsenate-bearing Fe-(hydr)oxides are of particular significance for the control of As mobility, as they are among the most thermodynamically stable minerals under near-neutral to alkaline pH conditions. However, in the surficial (upper 30 cm) alkaline mine tailings at the Cobalt...

... generally have higher gold and lower silver concentrations than the arsenide-bearing (cobaltite) sections, which tend to have higher silver values ( Table 2 and Fig. 6 ). As summarized in Table 2 , assays of high-grade vein mineralization from exploration pits and trenches on the property demonstrate...

In the following discussion we refer to all the arsenide and sulfarsenide minerals studied as ‘arsenides’ for brevity. The trace...
