The beakers were tightly capped and set on a hot plate at 130°C for 2 days to completely dissolve the pyrite. This solution was transferred to a 125 ml LDPE bottle, diluted up to 125 ml with quartz distilled deionized water, and analyzed on a Varian quadrapole ICP-MS against synthetic external standards using Ge, In, and Re as internal standards.

The pyrite dissolution results can explain the increase in gold dissolution after solution cyanidation. As the surface area of the gold exposed to cyanide solution also increases, the dissolution rate of the refractory gold-bearing pyrite increases. This explains the significant rate of gold dissolution with a D 80 of 12 µm. 3.4.

The main sulfur inputs to soils are from primary minerals, organic inputs and atmospheric deposition of sulfur. The primary soil minerals are gypsum (CaSO 4 ·2H 2 O) and pyrite (FeS 2) in igneous rocks, also known as fool's gold. Gypsum is highly soluble in acid soils, rapidly producing SO 42- ions.

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
