Fortescue - explaining the various cost and price metrics
Fortescue's delivered price is adjusted for its quality and lower ferrous content – it has historically been able to sell its product at an 85% discount to the index price. So if the iron ore index price is at US$58/dmt, Fortescue will be realising a price of about US$58 x 85% = US$49.3/dmt on its iron ore. C1 Cost.

Dry and Wet Screening in Mining: What are the Differences ...
If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you're missing several important points. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water. Extra plant capital is on the agenda when these additional stages enter the equipment line.
Difference Between Iron and Gold | Compare the Difference ...
Another important difference between the two is that gold is non-magnetic in nature whereas iron is highly magnetic in nature. Iron is chemically very active whereas gold is chemically inactive for that matter. It only means that gold resists individual acids but it can be attacked by the acid mixture aqua regia.

Iron Ore Mining | Techniques | Metal Extraction
Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
