Separating Pyrite & Blende Magnetism - 911metallurgist.com

At Kaslo, British Columbia, the Kootenay Ore Works operates a custom works on concentrate carrying galena, blende and pyrite carrying from 15 to 20 per cent. iron and rarely exceeding 37 per cent. zinc. The ore is delivered from railroad cars to bins at the top of the mill and after passing a sampler is fed to a White-Howell roasting furnace.

Pyrite: The mineral pyrite information and pictures

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.
