Pyrite Ore is a new resource that has been added in the Cataclysm expansion to the mining profession. In order to mine Pyrite Deposits players will be required to be at the new mining skill cap of 525 and be an Illustrious Miner. The deposit itself are only minable at skill level 525 so do not bother going to any of the zones below to mine Pyrite without the skill level.
Mar 19, 2013 The Iberian Pyrite Belt (IPB), SW Spain and Portugal, contains about 100 abandoned mine wastes and galleries that release acid mine drainages (AMD) to the Tinto and Odiel rivers. In situ passive remediation technologies are especially suitable to remediate the drainages of these orphan sites. However, traditional remediation systems, designed for coal mines, have been demonstrated …

Mining at North Island. Conventional truck and shovel method of mining will be applied at the Hushamu and Red Dog open-pit deposits of the North Island project. Mining is expected to be conducted at a rate of 64Mtpa, producing an average of 54Mtpa over the first 12 years.
Chemical mining may be defined as the in-place extrac-tion of metal values from ores located within the confines of a mine (that is, broken or fractured ore, stope fill, caved material, or ores in permeable zones) or ores located in dumps, prepared ore heaps, or tailing ponds. The term solution mining has, ingeneral, been used to mean the

What is Pyrite. Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.
