Jan 12, 2020· 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.

The laterite ore undergoes a reduction process at 525°C with carbon monoxide. This reduces nickel and iron to ferronickel, and the cobalt and copper to a metallic state. The minerals are then leached with a 100 g/L ammonium hydroxide (NH 4 OH), 300 g/L (NH 4 ) 2 SO 4 solution in a controlled oxidation leach to solubilise nickel, copper, and ...
