Magnetite Crusher

Magnetite mining, processing and value adding is much more intensive than the process required for the more traditionally hematite ore. Getting the ore out of the ground is the start of a more complex mining process. Once it has been extracted, it must go through a highly technical process to separate out and crush the magnetite into a concentrate – for direct export or for conversion into pellets.

magnetite process

The first stage is to feed the Magnetite ore through a primary crusher, located in-pit and can be jaw crusher or cone crusher. The crushed ore is then transported to a concentrator, which is comprised of a series of grinding mills and other processes. Each of the eight grinding mills stands over 17 metres high and 12 metres in diameter.

The grinding mills, such as SBM ball mill and Raymond mill, produce a fine magnetite ore stream that can be separated by magnetic separators to either concentrate or tailings. The resulting concentrate will be thickened and stored before being pumped 25 kilometres to the port, where it is filtered to reduce moisture.

Around 75% of the concentrate will be shipped direct to blast furnaces, with the remainder being processed into pellets. These pellets are able to be used as a feedstock to blast furnaces in the production of iron.

The concentrate and pellets will be a superior product for steel making because:

There is virtually no undesirable phosphorous
Less energy is required to process magnetite into steel in comparison to hematite
There is virtually no alumina
