1446 GMT - Shortages in sulfur caused by the conflict in the Middle East will raise costs for copper miners, J. Safra Sarasin's Asad Farid says. Sulfur is a by-product of oil and gas refining. It is used to produce sulfuric acid, which in is turn used in the leeching process by which miners extract copper from copper oxide ores. A significant proportion of copper miners' extraction costs are driven by the cost of sulfuric acid, Farid says. "There will be upward pressure on copper prices if this continues." Companies including Glencore and BHP have higher exposure to sulfuric acid price increases, though other miners will be less hurt as they mine copper sulfate ores, he adds.
