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

Cyanide Leaching and Decomposition of Pyrrhotite

Research on cyanidation methods brought considerable discussion on the reactions involved in the leaching and decomposition of pyrrhotite in cyanide solutions. Pyrrhotite has one loosely held sulphur atom which readily reacts with cyanide to form thiocyanate: Fe5S6 + NaCN = NaCNS + 5 FeS The ferrous sulphide oxidizes rapidly to the sulphate which reacts with cyanide to form ferrocyanide:

Supergene Gold In The Gold-Bearing Wastes Of Sulfide Deposits

The dumps of the pyrite-barite-polymetallic deposits of the Ursk ore field (Salairsky Ridge) have been studied by author. As a result of research, it was found that secondary gold enrichment horizon was formed at the bottom of the dump, and it consists of supergene gold. Gold morphology was studied using scanning electron microscopy.

The mineral pyrite (/ ˈ p aɪ r aɪ t /), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname

How to Test Ore or Rock for Gold Content

In all experiments aimed at testing the gold content of rocks or “ore”, you should ask yourself whether the conditions of his test differ in any vital particular from those that would obtain on a commercial scale; if so, there is no guarantee that his results would be borne out in a ing plant. Small scale experiments are very valuable if carefully and skilfully performed, but may be
