The gold ore is then washed down into sluices or troughs that have grooves to catch the gold. Next, cyanide is added to dissolve the gold, and then carbon is added to bond with the gold. After the carbon particles are removed from the pulp, they are placed in a hot caustic (corrosive) carbon solution, which separates the gold from the carbon.

President Brand, in effect, recovered an extra 0.15 gm gold per mt of ore (0.0044 oz/T), assuming 50% slolids slurry, by switching to high gold adsorption rate carbon. To put carbon costs in perspective, it is useful to consider the amount of additional gold it is necessary to recover to offset the cost of using high activity carbon.
