Refractory Gold Ore Treatment Methods
Graphite is present in the gold-silver ore in the Timmins Ochali Mining Co, mill in Columbia. It was noted that considerable carbonaceous schist occurs in the run-of-mine ore, not all of which is detrimental.

STUDIES IN THE PROCESSING OF A CARBONACEOUS GOLD ORE
that gold could be separated from graphite by flotation in a xanthate-starch-02 system. In the third part, some of the processes for treating the ore have been studied. These include the flotation of gold and graphite, and the carbonaceous gold ore with xanthate, starch and quebracho. The results are in agreement with earlier predictions.

Gold and Other Metals in Graphite SpringerLink
Gold, in particular, becomes concentrated at vein margins, suggesting a hydrothermal transport mechanism and accumulation by carbon. It has been postulated that graphite becomes activated at the vein margins under high temperature conditions and it is this activation that provides sites for the accumulation of metals.
