The term "milling" refers to the manufacturing process of using a circular cutting tool on the ends and sides of a material blank to make a finished part. That's obviously just a very general summation; there are actually around …
What is Magnetite?
Magnetite is mined at the Xstrata Copper Ernest Henry Mining operations in the north west of Queensland. The orebody is an iron oxide- copper- gold deposit with magnetite being the form ... which requires further milling so that the magnetite can be liberated and extracted. Un-liberated magnetite is usually larger than liberated
Processing
Sino Iron's processing plant is where we transform the magnetite ore into high quality, premium magnetite concentrate. This is the heart of our operation at Sino Iron. Before the ore arrives at the processing plant via the conveyor, it's already been reduced down at the in-pit crushers to roughly the size of house bricks.

13 Milling Operations Explained with Applications
In face milling operation the teeth present on the milling tool periphery remove the majority of the material.. At the same time, the face of the tool finishes the surface along with minor material removal. The milling tool is perpendicular to the workpiece, so when the cutter rotates, the workpiece is fed against it, resulting in material removal.
