what is yield rate in iron ore processing
The chemistry of steelmaking. The big picture.
Iron is a moderately reactive metal which joins readily with nonmetals such as oxygen. This is why we do not find pure iron in the Earth's crust. Instead it is found as an ore, in which iron is chemically combined with oxygen or other nonmetals. Most workable iron ores are rich in iron (III) oxide, Fe 2 O 3. Making iron by removing oxygen ...

Direct Reduced Iron (DRI)
Directreduced iron has about the same iron content as Pig Iron, typically 90–94% total iron (depending on the quality of the raw ore) as opposed to about 93% for molten pig iron, so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel.

Mining yield
· Mining yield. Mining yield is the rate at which miners mine ore, ice, or gas. As all mining modules mine a certain volume of ore/ice/gas in a given time, the amount of ore/ice/gas mined therefore depends on this mining rate (often quoted in m 3 per minute) and .
