In this work, a calcination procedure for Se -enriched slate using CaO as a sorbent was developed, and the process significantly improved the bioavailability of Se. The calcination experiments were conducted with the calcium (Ca)-based sorbents CaO or CaCO3 at 300-800 degrees C. Most of the Se in the organic matter and sulfides were emitted between 400 and 650 degrees C, and CaO exhibited a higher adsorption efficiency of Se compared with CaCO3. The optimum temperature was 600 degrees C as determined by the high contents of bioavailable Se (10 times that of the original slate) and Se(VI) in the calcinated samples with the sorbent CaO. Both the physical adsorption of CaO and the formation of CaSeO3 contributed to the conversion of Se associated with organic matter and sulfide minerals to bioavailable Se species. The transformation of Se(IV) to Se(VI) might have been caused by the co-oxidation of O-2 and the generation of HCl during the calcination process. The Se concentrations in potatoes amended with activated slate reached 650 +/- 23 mu g/kg, which verified the high Se bioavailability of the calcinated product. The proposed calcination procedure could support the exploitation of Se -enriched slate and the preparation of Se soil amendments. (C) 2016 Elsevier B.V.

This study investigated the geochemical characteristics of Se and its fractions in Se-enriched rocks from Ziyang. Se distribution is uneven, ranging from 0.23 to 57.00 mu g/g (17.29 +/- 15.52 mu g/g). Se content is higher in slate than chert, and even lower in carbonate rocks. Cd, As and V are enriched but Pb is depleted in Se-enriched strata. Se has different correlations both with TS (total sulfur) (R-2=0.59 for chert) and TC (total carbon) (R-2=0.77 for slate, R-2=0.87 for carbonate). Se has significant positive correlations with V (r=0.65), As (r=0.485), Cd (r=0.459) and Pb (r=0.405). The Se level correlates with mineral content, positively with pyrite, chlorite and illite, negatively with albite. Se associated with sulfide/selenide and elemental Se are the predominant fractions of total recovered Se, suggesting that a reducing environment and the formation of sulfides were significant to Se deposition during its geochemical cycle.

Ultrafine powder particles produced by wet milling were characterised as d50: ~ 1.0 μm, d90: ~ 5.0 μm. Agate abrasion (balls and vial) during wet milling affects only SiO2 measurements and is negligible for other elements. For the flux‐free fusion glass, a second grinding of the initial fused glass and re‐melting were necessary to produce compositionally homogeneous glasses. Nickel and Cu can be contaminated during the fusion procedure, and Sn and Pb were depleted after the melting process. The homogeneity of fusion glasses was comparable to that of MPI‐DING glasses, while the powder pellets were less homogeneous. This heterogeneity is ascribed to large (up to 10 μm) crystal fragments (e.g., biotite) persisting in powders even after 45 min of milling. For most elements of interest, both preparation techniques give reliable LA‐ICP‐MS results of granitoid reference materials within 10% of the reference values. Thus, we can recommend both techniques to avoid common problems associated with acid dissolution ICP‐MS.
