The Step-by-Step Process of Producing Iron from Iron Ore
The raw materials mix or "charge" enters the furnace from the top and hot air is blown or blasted from the bottom causing the coke to burn and the oxygen to combine with carbon in the coke to form carbon monoxide. Now, this carbon monoxide that is unstable, reacts with the ore to form carbon dioxide and iron. The Separation Of Iron-.

2.1. Introduction. Iron is estimated to make up 32.07% of the Earth's mass and its elemental abundance varies between about 5% of the Earth's crust and as much as 80% of the planet's core (Morgan and Anders, 1980).It is therefore not surprising that there are a number of commonly occurring iron minerals and many iron ore deposits found at the …

The six main steps of iron ore processing
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. This step prevents overloading the crusher and increases its efficiency.

DRI retains the chemical purity of the iron ore from which it is produced. It therefore tends to be very low in residual elements such as copper, chromium, tin, nickel, and molybdenum. Typical ranges of DRI chemistry are 90–94% total iron, 83–89% metallic iron, 6.5–9% iron oxide, 0.8–2.5% carbon, 2.8–6% gangue, 0.005–0.09% ...
