The mining industries covered in this manual are: coal, iron ore, bauxite, copper ore, gold ore, nickel ore, silver-lead-zinc ore, uranium ore and other metallic ores. EET MANUAL:
Jun 25, 2019· Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BC.
The Environmental Code of Practice for Metal Mines describes operational activities and associated environmental concerns of this industrial sector. The document applies to the complete life cycle of mining, from exploration to mine closure, and environmental management practices are recommended to mitigate the identified environmental concerns.
The slag contains less than 0.5 % Cu. The off-gas from the blast furnaces (three in each plant) is mixed with the converter gases (Hoboken Converter). It contains 7 – 10 % SO2 and is sent to sulfuric acid production. The production figures are 80 000 t/a converter copper in Legnica, and 200 000 t/a in Glogow I Smelter . 5.4.2.
