Iron Ore Grinding Process In Australia

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore

Sep 01, 2018 Gao et al. (2015) emphasised the need for fine grinding of oolitic iron ore ahead of reduction using blast furnace gas (42% CO) in a rotary furnace at 900 C followed by magnetic separation at 0.1 T. Metallisation was only 40% for particles less than 0.13 mm, but jet milling down to less than 10 m ahead of reduction roasting at 900 C

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on run-of-mine ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition

IMP Technologies (IMPTEC) has anticipated the need for a dry low cost processing alternative which can open the way for the development of lower grade magnetite deposits and ensure the sustainability of processing in Australia. The lower grade magnetite deposits are generally fine grained and require grinding to p80’s of 30 to 40 microns

Australia's hematite DSO from the Hamersley region in Western Australia averages from 56% to 62% iron. Like hematite ores, magnetite ores require initial crushing and screening, but undergo a second stage of processing that relies on the magnetic properties of the ore and involves magnetic separators to extract the magnetite and produce a concentrate
