Both technologies are already implemented in some magnetite processing operations, although in limited capacity. The results of a theoretical option study for high capacity processing of a hard, fine-grained silica-rich magnetite ore is presented in this paper, with the emphasis on comminution circuit options.
8.1. Introduction. Hematite and magnetite iron ores are the most prominent raw materials for iron and steel production. Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO).

The description of the SFC, its mode of operation, and how its operational parameters affect its performances have been presented by Baawuah et al. [18], Batterham et al. [19], and Kelsey et al. [20].
Magnetic separation equipment is widely used in the separation of magnetic minerals. Low-intensity magnetic separator is mainly used for the separation of minerals with specific magnetic susceptibility greater than 1 × 10 −6 m 3 /kg, such as magnetite, vanadium titano-magnetite, pyrrhotite, and other minerals. Medium-intensity magnetic …
The present study investigates the economic and socio-environmental benefits of applying these technologies in conceptual dry magnetite ore processing …
Magnetite production accounted for 45.6% towards water consumption in the cement kiln operations. During magnetite beneficiation in a wet process, water consumption is high (Baawuah et al. 2020) . ...
A total of A$2.8 billion in goods and services have been sourced within Western Australia for the Iron Bridge project and operations, including over A$285 million awarded directly to Nyamal businesses since 2020. Commissioning of the OPF is progressing well on site. Load commissioning commenced on the dry process in early …
A novel low-intensity pneumatic planar magnetic separator designed to recover and concentrate fine-grained magnetite minerals is investigated and the …
During operation, the dry feed is transported by pressurised air at a pre-set velocity through the separation chamber, where magnetic particles are recovered and separated from the nonmagnetic particles. ... Recovery of magnetite from dry crushed feed using wet low intensity drum separator; Baawuah, E., Kelsey, C., Addai-Mensah, J., …
Karara is the largest mining operation in the Mid West region and one of only two operating magnetite mines in WA. The Karara Iron Ore Project is located 220 kilometres south-east of Geraldton in the Shire of Perenjori. ... Tailings material generated in the ore treatment process is filtered for dry tails stacking where possible, reducing ...
Economic and SocioEnvironmental Benefits of Dry . For example, Australia is the driest continent globally and is home to some of the largest magnetite production in the world Examples of magnetite operations in Australia are Savage River, Karara, SIMEC Mining, and the Sino Iron Project
, and 95.1 wt% of magnetite. The Blaine specic surface area was 2300 cm 2/g, being in the range recom-mended for pelletizing (1900 up to 3000 cm2/g). The total mass, Fe, SiO 2, Al 2 O 3, and magnetite recoveries were 2.77%, 29.71%, 0.09%, 0.12%, and 73.17%, respectively. Most of the magnetite losses, around 20% of total magnetite fed, occurred
The study demonstrated that the use of PMS in the dry beneficiation of magnetite ores is feasible, and operating the PMS in different flowsheet configurations positively influences the magnetite ...
Iron-containing ore beneficiation includes several stages. For example: crushing to −30 mm size class and rough magnetic separation, further crushing of the …
When fine-grained magnetite is the only mineral of value and there is a minimum of dilution rock and barren material in the ore, elimination of cobbing in the crushing plant in favor of wet rougher magnetic separation in the grinding circuits should be considered. Sampling of a cobbing plant is always difficult when treating coarse material.

Iron ore magnetite processing (LIMS, MIMS, WHIMS, Davis Tubes) The increased worldwide demand for steel in recent decades has led to an increase in the exploitation of magnetite iron ore deposits as an alternative to hematite DSO ores. Magnetite concentrate is a higher-grade product than hematite and very desirable as a smelter feed.

Dry, coarse tailings do not require tailings ponds but can be dry stacked. It makes a lot of sense from an economical and environmental point of view to pre-process magnetite in a dry state whenever possible. Pre-concentration is often referred to as cobbing or sorting.
