Magnetite is the most magnetic mineral, and has been used as a lodestone or natural magnet in compasses in the past. As it is dense with a specific gravity of over five, it is used as a dense medium when mixed in mineral separation particularly in coal preparation. Importantly, magnetite is suitable for processing into iron ore
Magnetite ore and processing. A general processing circuit for magnetite ore is initial crushing and screening of run of mine (ROM) ore to <6 mm. The ore is then milled to a specified grind size to liberate the iron minerals from the gangue, then processed further to produce a magnetite concentrate, commonly by a wet magnetic separation process

2.44 million ton[1], and Lampung magnetite ore deposits have been ident ified as a potential industrial resources [2]. Magnetite ore is commonly extracted from earth as the primary raw material to produce sponges iron or iron pellets for steelmaking industry. However, most Indonesian magnetite ore deposits are
Although the majority of current steel production is supported by iron ore sourced from high-grade haematite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed. There is a rich and long history of magnetite ore processing in Western countries, including large …
The results of early laboratory test work on the development of an efficient and environmentally sustainable dry processing option for the beneficiation of lower grade magnetite ores were tabled by IMP Technologies Pty. Ltd. (IMPTEC) and Cyclomag Pty.Ltd. at Iron Ore 2017 in Perth W.A. Since that time, the companies have experienced increasing demand for laboratory testing of …
crushed hematite or magnetite ores without additional thermal processing of the magnetite ore. Australian iron ore. Australia has 58,286 million tonnes of Economic Demonstrated Resources (EDR) of iron ore (Table 1), ranking first in the world with 31% of world economic resources. 2. Australia is also the world's leading
Banded magnetite quartzite (BMQ) ore occurs as separate veins in iron ore mines and recovered while mining the natural hematite ore. In India, such ores are considered as low grade iron ores with Fe content of 25–45%, SiO 2 30–60% and Al 2 O 3 1–5%. No commercial plant has been set up so far to recover the iron values from such ores for any industrial …
The ore will be crushed and processed at the site for the production of magnetite, dry process rejects, and wet tailings. The processing plant will use dry crushing and grinding circuit. The plant will employ the KB 63-130 type …
In magnetite ore processing plants they have found application for silica control at the end of the circuit as silica is present in a coarser particle size range than magnetite and therefore can be removed by fine screening. (Staton et al., 2015). Most recent installations ...

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
In this research, the mechanism of the original magnetite improving iron ore reduction during the magnetization roasting process was explored using ore fines and lump ore samples.
