I have been doing some research into carbon in Leach ( CIL) , here in WA.

I can confirm one gold producer uses circa 3,000 Kgs per month, and pays circa$ 3.00 per kg, for their activated carbon.
So I think this puts Ionic's Super Sand in the race.

" The properties of activated carbon that are critical for plant performance are:  rate of gold adsorption (kinetic activity),  amount of gold loaded onto carbon (equilibrium capacity), and  resistance of the carbon to fines formation (attrition resistance).  Commercial products are supplied in specific size ranges and made from coconut shells or extruded carbon based on peat or coal. Quality of the Carbon made from coconut shells can vary with respect to activity and strength. "
