First, moistened concentrates are fed to a rotating drum or an inclined disc, the tumbling action of which producessoft,spherical agglomerates. These “green” ballsare then dried and hardened by firing in air to a temperature in the range of 1,250° to 1,340° C (2,300° to 2,440° F). Finally, they are slowly cooled.

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.

Iron processing-Iron processing-Ironmaking: The primary objectiveof ironmaking is to releaseironfrom chemical combination with oxygen, and, since the blast furnace is much the most efficientprocess, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percentof ironis made this way.

Jun 22, 2018· Themining processcan be broken down into two categories: SurfaceMining. Workers begin by striping the overburden, which is rock, soil, and ecosystem that lies above the surface. Undergroundmining. The digging of tunnels and sink shafts when the ore—or mineral deposit—is below the surface. Hand tools such as chisels, hammers, and wedges ...

Theprocessof extractingironfrom ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproductof ironpurification is slag, which is produced in huge amounts.
