Iron ore mining and dressing
After the coarse ore has been extracted, it is crushed directly at the deposits with the aid of cone crushers or jaw crushers to more manageable sizes of approx. 15 mm. This is also known as lump ore. In addition to lump ore, fine ore (approx. 1 mm) and ground ore (ore powder) (approx. <0.1 mm) can also be obtained by crushing and grinding.

Crushing And Grinding Of Aluminium
The journey to extracting aluminum begins with the primary step of crushing the aluminum ore, also known as bauxite. Bauxite ore is usually sourced from open-pit mines and is extracted using various techniques. Once collected, it undergoes a series of crushing stages to reduce its size and facilitate the subsequent grinding process.
