"There's gold in them there hills!" On a recent trip to Sutter's Mill in Coloma, CA, we got a chance first hand to discover actual gold and learn how to tell the difference between the real deal and tricky fool's gold. Without zooming in, it can be tough to tell the difference, especially when the sun is shining and the water makes everything glisten.
Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides. This may be an alternative treatment route for gold room applications where fine gold losses can occur when treating gravity concentrates with pyrite and copper sulphides present.
The ore consisted of quartz, in which, above the 250-ft. level, the iron-minerals were largely oxidized and some free gold was visible; below that level few traces of oxidation occurred, and pyrite constituted the principal mineralizer in the quartz, together with occasional pockets of galena and a few eccentric specks of covellite. The 20-stamp mill was equipped with plates for amalgamation ...

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 may conveniently be considered here.
