Froth Flotation of Iron Ores

 · With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century''s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Avoided energy cost of producing minerals: The case of ...

 · Thus, the total specific energy for concentrating iron ore at the average ore grade (∼ 50% iron) from Thanatia (3.63% iron) was considered as the sum of the energy for the ore-handling process and the energy for concentration. In our model, the minerals for concentration are obtained from Earth''s crust; surface mining is assumed.

Cost Accounting in Mining

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.
