Processes and Procedures in the Extraction of Iron ...

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes …

What Are the Advantages of Wet Grinding vs. Dry Grinding?

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
