Case Study Methane Recovery at Non coal Mines

Existing methane recovery projects at non coal mines reduce greenhouse gas (GHG) emissions by up to 3 million tons of carbon dioxide equivalent (COe). Although methane emissions are generally associated with coal mines, methane is also found in salt, potash, trona, diamond, gold, base metals, and lead mines throughout the world.

Spontaneous Combustion Management Acid amp; Metalliferous

Spontaneous combustion is a process that affects a broad range of mining operations, including gold, silver, copper, lead zinc, nickel, tin, iron ore and coal (brown and black). The process is initiated by the spontaneous oxidation of extremely reactive iron sulfide minerals (largely pyrite, marcasite or pyrrhotite), in a highly exothermic process that generates sulfur dioxide gas (SO 2 ) a sulfide fire.
