A slurry pipeline is a specially engineered pipeline used to move ores, such as coal or iron, or mining waste, called tailings, over long distances. A mixture of the ore concentrate and water, called slurry, is pumped to its destination and the water is filtered out.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

Most of the material continues to be finely ground in one of five secondary ball mills, which are powered by electric motors ranging from 2,500 hp to 4,000 hp and are charged
Iron ore slurry filtering solutions. Iron ore is ground to finer particle sizes through different grinding systems. Large grinding mills using grinding ball media are one of the most common and particularly in pelletizing plants where finer particle size are required for the pelletizing process. Those large mills operate either with water mixed
Slurry transportation of iron ore concentrate through pipelines is an environment friendly method for ore transportation.
