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 nonamalgamable gold its physical state and the causes of its disinclination to unite with mercury may conveniently be considered here
