  • How can you extract iron ore from iron pyrite - Answers

    Also, it is much more economical to extract iron from other minerals. Pyrite is also geologically unstable, and will eventually turn into sulfurous minerals and actually viable iron ores, so it is ...[...]

  • How do you separate gold from pyrite without a smelter ...

    Gold and pyrite look similar, yes, but gold has a higher density than pyrite, this would make the gold heavier than a piece of pyrite the same size. Also gold is also softer than pyrite.[...]

  • CN104263961A - Method for extracting gold from pyrite ...

  • How To Get Sulfur - Primitive Skills

    Nearly all pieces of pyrite are formed into the shape of crystals. You probably know that gold is one of the heavier metals. Panning for gold relies on this property of gold. Pyrite weighs less than gold, and small flakes of pyrite will wash away when placed under the water. To extract the sulfur from pyrite (53% Sulfur) or other rocks such as Galena (13% Sulfur), can be done using a two pot distillation method.[...]
