Where the main gold bearing refractory mineral in the concentrate is pyrite, the oxidative leach is typically carried out under alkaline conditions. The leach conditions are set to ensure the formation of goethite as the major iron reaction product.
Commonly called fools gold, pyrite is the Earths most abundant sulfide mineral. Recognized for its brassyellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

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 thises 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
