The gold flakes are very small in size, 510 microns. The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).

Evidence of hydrothermal mineral deposits were first noticed in 1948 during the Swedish Albatross oceanographic expedition in the Red Sea. This was followed by discoveries of metalliferous muds and brines in 196366 in the Red sea Rift system. These metalliferous muds contained large amounts of copper, zinc, lead, iron, silver and gold.

 · Recover Gold by Roasting Pyrite Ore. The roasting of straight pyritic ores involves the conversion of the iron sulphides to the oxide under oxidizing conditions with the evolution of sulphur dioxide and, to some extent by alytic action, sulphur trioxide gas also. In this chemical change the iron mineral is rendered more or less porous, thereby permitting the dissolution of the contained ...
