When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.

Banded iron formations are known as taconite inside North America. The mining includes moving enormous measures of metal and waste. The waste comes in two structures, non-metal bedrock in the mine (overburden or inter-burden privately known as mullock), and undesirable minerals which are a characteristic part of the metal shake itself (gangue).

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.

The method does not use water to process iron ore, instead it transforms mining tailings - with low iron content and no commercial value - into high iron content and low contaminants, making it economically viable. As iron ore must be composed of grades of at least 58 per cent, mining companies stack the lower grade material on tailings dumps.

Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.
