Improved recovery of a low-grade refractory gold ore

A moderately low grade of the bulk ore and the additional processing costs involved in whole ore treatment processes are most certainly not economically viable and therefore not being considered . A significant proportion of the sulfidic refractory gold appears to be hosted by the arsenical pyrite, arsenopyrite and stibnite components of the ore.
