1. Introduction. In the past 25 years, most of the development in the cyanidation of gold has occurred in response to the decreasing grade of deposits, the shift from surface mining to underground mining, the increasing complexity of treatment, and the concern for environmental constraints.Research has focused on the use of new equipment such as the IsaMill to liberate gold …

XANES spectra of chemically bound gold in all natural and synthetic arsenopyrite, löllingite and As-rich pyrite (≥1 wt. % As) samples examined here significantly differ from those of metallic Au 0 and other reference compounds in which Au is coordinated by 2 to 4 As/S/Cl atoms or by 6 Sb/Te atoms, implying a different Au local environment in sulfarsenides (Figs. 1, S-6).

The application of SEM-EDS microanalysis in the characterization of gold-bearing ore composition indicated that the gold grains were mostly a gold-silver alloy with an average composition of 71% gold and 29% silver (varying from 2.4% to 69.4% Ag and 30.6% to 97.6% Au).

The Iberian Pyrite Belt (IPB) is recognized as having one of the major concentrations of volcanogenic massive sulfide (VMS) deposits on Earth. Original resources of about 2000 Mt of massive sulfides have been reported in the province. Recent classifications have considered the IPB deposits as the bimodal siliciclastic subtype, although major differences can be recognized among them.
