pyrite roasting an alternative to sulphur burning
Roasting of Pyrite Pyrite, or iron sulphide, is roasted in various types of furnaces, multiplehearth furnace, rotary kiln and fluid bed roaster, producing a gas with a somewhat lower sulphur dioxide content than the combustion gases from burning elemental sulphur.

mining pyrite raymond
Pyrite and Coal Mining. Sulfur occurs in coal in three different forms 1) organic sulfur, 2) sulfate minerals, and 3) sulfide minerals (mostly pyrite with minor amounts of marcasite). When the coal is burned, these forms of sulfur are converted into sulfur dioxide gas and contribute to air pollution and acid rain unless they are removed from the emissions.
Guidelines for Validation of Dry Roasting Processes
Dry (hot air) roasting is a thermal process used by the almond industry. A dry roast can be achieved via a continuous conveyor roaster or rotary roaster. The continuous conveyor roaster can be singlestage or have multiplestages with a variety of temperature controls. Common temperatures used for hot air roasting range from 265°F to 310°F.

Arsenopyrite an overview | ScienceDirect Topics
In the case of mesothermal pyritic gold ores, pyrite and arsenopyrite are sufficiently coarse grained, which allows for good liberation at modest grind fineness (P 80 of 75–120 μm) and results in highgrade concentrates with good recoveries. In some of these ores, submicroscopic gold is exclusively carried by arsenopyrite, which makes separation enticing from the barren pyrite (Donlin Creek ...
