Sulfides, Selenides and Tellurides: rebellious and

Well, sulfides, selenides and tellurides are simply minerals which contain sulfur, selenium, and tellurium combined with some metal. Unusually this is the metal we are interested in, but sometimes other valuable metals can be mixed in as trace elements. An example of this is when gold occurs disbursed through a crystal of pyrite.

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.
