By today’s standards, nearly all of the pre-World War II iron ore produced would be considered “high grade.” Ore was shipped directly from the mines to the iron furnaces. From the 1880s on, an increasing number of concentrators began operation. They typically used gravity separation methods (crushing, screening, washing, and drying) to

Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.

Iron was probably first produced by the Hittites about 1500 B.C. This metal cannot be separated from its ores by heating alone; extraction requires the presence of carbon. Perhaps the chance combination of charcoal with iron ore, probably in a camp fire, led to the discovery of the process of purifying iron.

The other two work towards making the ore easier to smelt – by transforming the ore into a reducible form, and increasing the surface area of the ore. Washing. Iron smelting might not be the cleanest of operations, yet washing does come into play at some point. Iron ore recovered from the ground generally comes covered in dirt.

Hydraulic Washing. This method is based on the differences in weight between the gangue and the metal. Generally, the metal particles of the ore are heavier than the impurities. So we use the principle of gravity separation to separate the two. Here crushed ore is mixed with an upward stream of running water.
