Iron Essential Chemical Industry ball mill

Iron is produced by reduction of iron ore, which is often a mixture of oxides, using carbon, carbon monoxide, and hydrogen ball mill. While the blast furnace is the dominant reduction process other technologies are emerging which operate on a smaller scale. These are linked to locations where there is a plentiful supply of natural gas or low-grade coal ball mill.

Manufacture of Steel Steel Manufacturing Process and Steps ball mill

Jun 06, 2017 The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace ball mill. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace ball mill. ball mill
