As I understand your posts, there is both free milling gold and gold tied up with other minerals in the ore you are currently working. That said, is the other than free milling gold of significant value or are there other minerals of more value? In other words, it may be a better solution to concentrate the other minerals after separating the free milling gold. On a commercial scale, a smelter will process (use copper concentrates for example) and pay for silver and or gold credits, if they are at or above a minimum payable value (usually assayed in OPT in the concentrates), in the final settlement. That was what was in the smelting contract for copper concentrates produced by the mining company that I used to work for. On a side note; the gold and silver in the smelted cathodes is recovered at a copper refinery using an electrolytic process as best I can recall.
Good luck.
