Chemical speciation of gold in arsenopyrite
, 2000 The speciation of Au in gold-bearing arsenopyrite (FeAsS) from four gold deposits (Olympiada, Sentachan, Sao Bento and Sheba) was determined by micro-X-ray absorption near-edge structure (XANES) on grains well characterized microscopically and by ...

Известия Томского политехнического университета: Инжиниринг георесурсов, 2022 Relevance. The Chertovo Koryto is located within the Lena gold-bearing province, in which large reserves of gold deposits are concentrated (Sukhy Log, Verninskoe, Vysochayshee, Ozherele and other). A lot of time was devoted to the study of this province,

Mineralogy of Historic Scheelite Mine Tailings at Glenorchy, Otago, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Otago Schist orogenic mineral deposits with scheelite and gold in the Glenorchy area are mineralogically and geochemically similar to, but structurally different from, those at the active Macraes gold mine in East Otago. Glenorchy veins were mined for scheelite up to 1970s, and an abandoned processing battery site at Glenorchy is now being managed for ...
