Processes for phosphorus removal from iron ore

2.1 Phosphate occurrences. Iron ore of high phosphorus content coexists with other minerals in the form of apatite or fluorapatite. Phosphorus is spread on the edge of mineral particles of iron oxide and embedded in quartz or carbonate minerals and a small amount is present in the iron mineral grid (Xia et al., 2011).The most frequent and important constituent of the class of phosphates is ...

Metal Profile: Iron Properties and Characteristics

2020-1-12 · History . 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 behind 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 BCE.
