Abstract: Building on work completed in earlier papers, the current paper presents a techno-economic evaluation of two recently demonstrated technologies for treatment of arsenic containing refractory gold concentrates. Using defined project parameters and inputs, the authors compare capital and operating cost estimates for pressure oxidation (POx), and the Albion Process™. The paper incorporates data now publicly available from the Albion Process™ plant, which has operated at the GeoProMining Gold (GPM Gold) project in Armenia since 2014, as well as recent POx circuits.
TL;DR: In this paper, a conceptual design for producing 300,000 tpa zinc directly from McArthur River bulk concentrates is presented, taking into account the availability of natural gas and the associated increasing importance of Darwin as a hub for natural gas from the Timor Sea.
