the mill grinding chamber, in which the vertical agitator screw is located, together with a charge of grinding media and grinding material in slurry form. High-growth markets in copper, iron-ore, gold, lead-zinc ores, mineral sands and rare-earth metals drive increasing demand for fine grinding to maximize recovery.
Karara Mining Limited is a joint venture between Gindalbie Metals Limited and AnSteel, one of the largest iron ore producers and steel makers in China.Located 200km south-east of Geraldton, Western Australia, Karara is the largest mining operation and the first major magnetite mine in the Mid-West.
S Palaniandy, R Halomoan and H Ishikawa 14thAusIMM Mill Operators' Conference, 29-31 August 2018, Brisbane, Australia ABSTRACT The Karara iron ore project is a magnetite operation consist of open pit mining and concentrator to produce high-grade magnetite concentrate.
The crushed ore is then transferred to the Coarse Ore Stockpile (COS), which has a holding capacity of up to 500,000 tonnes of material for downstream processing. Ore material from the COS is reclaimed by conveyor into a parallel train of two High-Pressure Grinding Rolls (HPGR's), which grind the ore to a size of 4 mm or smaller.
Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines' autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.

The Karara mine is a large iron mine located in the Mid-West region of Western Australia. Karara represents one of the largest iron ore reserves in Australia and in the world, having estimated reserves of 2 billion tonnes of ore grading 35.5% iron metal. It is one …
In this study, a 120 L ceramic-medium stirred mill was used to conduct experimental research on the pilot-scale grinding study of raw ore. Table 1 showed the equipment parameters of ceramic-medium stirred mill. The effects of material ball ratio, medium size and proportioning, stirring speed, grinding concentration, and medium filling rate [,,, ] on the stirred mill grinding were …
Karara's ore is mainly supplied to Ansteel, who entered the joint venture to establish an integrated supply chain. Karara's ore processing facilities include four grinding mills which use 50mm grinding balls and five tower mills which use 20mm grinding balls. The grinding circuit reduces the ore from approximately 60mm to 25 microns.
