As can be s reducing particle size from −200 + 100 µm to <75 µm leads to an increase in iron g from 27% to 33%, whereas the iron recovery diminishes from 96% to 73%.
Mineral size recovery curves in spirals are calculated using data from two iron ore processing plants.. Recovery of iron carrier particles increase up to 0.2 mm and then decreases due to the Bagnold force.. The decrease of recovery for coarse silica carrier particles is more important than that of iron carrier particles.

1. Introduction. Iron-containing ore beneficiation includes several stages. For example: crushing to −30 mm size class and rough magnetic separation, further crushing of the recovered magnetic product to −10 mm size class and final magnetic metal content upgrading. All operations use dry methods.
Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity …
It is a potential dry magnetic separator for oxidized iron ore beneficiation. 9.6. Summary. The majority of iron ores occurring naturally on earth are low-grade and need to be upgraded prior to use in metallurgical processes. Magnetic separation is the most important method for upgrading low-grade iron ores to high-quality iron ore …
