    Double Refractory Carbonaceous Sulfidic Gold Ores

    During the roasting process of double refractory ores in the presence of oxygen, the main reactions are the combustion of the carbonaceous material and sulfides. It is estimated that 8189% of the TCM content in the ore is oxidized, producing carbon dioxide (about 96% of the carbon by weight) and carbon monoxide (about 4% of the carbon by weight).

    Adsorption of aurocyanide complexes onto carbonaceous

    Aurocyanide complex adsorption by naturally occurring carbon in Goldstrike ore has been implicated in a form of gold refractoriness known as Apreg robbingB. The aim of this work was to establish a relationship between the aurocyanide uptake capacity of Goldstrike ore carbonaceous matter and the preg robbing behavior of the parent ore.

This basin and range topography formed due to compression and extension by global tectonic forces and the thinning the underlying crust. This produced curved faults, known as listric faults that level off at depth. This faulting also produced the hills and valleys throughout the region.
