Pool acid will not work and I'm not sure any single acid will either. One acid might attack the quartz and leave the limonite and the gold. Another acid might attack the limonite and leave the quartz and gold. I guess you could try and use both separately but I'm not sure what your intentions are. Steve
A similar case was noticed by Mactear in South America, where a limonite ore which only yielded from 35 to 40 per cent, of its gold when treated in Huntington pans, was made to yield between 85 and 90 per cent, by merely subjecting it to a dehydrating calcination before amalgamating it.

How to Separate Gold from Pyrite. So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier Nevertheless, as this gold comes under the head of non-amalgamable gold, its physical state and the causes of its disinclination to unite with mercury ...
In production, most limonite processing plants will use the washing-gravity separation process flow to separate limonite and martite. First step, we use the trommel screen washer, chute washer and scrubbing machine to wash the ore, then we use a heavy medium and jig machine and other gravity separation equipment for separation.
The second process is desludging and disintegration. Desludge and disintegration actually doing the same job, that is, by sand-washing, mechanical scrubbing and other progress, the gold and mud in the mine are fully diluted to prevent the gold from being wrapped in the soil, this ways make the gold to be freed so that the gold can be recovered.
