China's state planner issued on Wednesday its third warning this month against excessive speculation in iron ore, adding that it will increase supervision of the country's spot and futures markets. If two iron amounts are listed on the label, the larger number is the chemical compound form because iron is bound to salts (e.g., ferrous sulfate), whereas the smaller number refers only to the amount of iron in the compound, also called the elemental iron.
