Cortez is approximately 113km south west of Elko, Nevada. It consists of three distinct units: the Cortez open pit and two Carlin-type disseminated gold deposits Pipeline and South Pipeline. Until February 2008 the operation was 60%-owned by Barrick Gold, having acquired Placer Dome for US $10.4bn in 2006, and 40% by Rio Tinto.The flake size distribution significantly affects the value of graphite products. The graphite grain size distribution was determined using the thin section identification method [27] based on the polarized optical microscope with the lump graphite sample described above. The results are shown in Table 2.A total of 69.50% graphite An innovative flake graphite upgrading process based on

Currently, Find, read and cite all the research you needAt current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5.
