Potential for saving over $100 per ounce
Increased gold recovery (no loss to AC fines or solution loss); recent field tests showed as much as 10% more gold recovered, with essentially zero solution loss
Higher capacity and selectivity translates to smaller plant and lower cost of operations
No significant performance changes through many cycles
Demonstrated to be highly effective with preg-robbing ores
One step elution at low temperature and standard pressure
The vast majority of gold mines currently use coconut-based activated carbon (AC) for recovery of gold from cyanide leach solutions. These mines typically use carbon-in-pulp, carbon-in-leach, and, to a lesser degree, carbon-in-column systems to extract gold. While these systems have been perfected over 100 years of use, AC has inherent limitations. Capacity for gold adsorption is highly dependent on the metallurgy of the ore, quality of the AC, pH of the pregnant solution, and other factors.
IXOS® nanotechnology shows stable and predictable performance across a wide variety of conditions. Gold capacity and selectivity remain significantly higher than AC regardless of the presence/levels of other base metals. Moreover, superior mechanical strength over AC allows for virtually 100% gold extraction with no loss to fines. The IXOS® beads don’t become poisoned with other base metals; they fully elute; and are re-usable for dozens of loading and unloading cycles.
