Dry beneficiation of iron ore Mineral Processing
The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years.This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores.

DRY MAGNETIC SEPARATION OF MAGNETITE ORES
2 天之前The study of beneficiation indicators of the magnetic separator was carried out using iron ore of the Bapy deposit, which is mono-mineral magnetite. For the study, mixtures of the minus 0.1 mm class were selected with the iron content α = 50% and α = 40%. So far, dry magnetic separators have developed many different applications foroptimization of dry magnetic separators.

Comminution and classification technologies of iron ore
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).It is possible to increase the iron content of the ore from 42% to 53% Fe by using dry magnetic separator. In these fractions the Fe recovery is in the range of 80–89% and yield is in the range of 60–70%. In case of finer size fractions such as −0.500 to +0.300 mm, it is possible to increase the iron values from 44% to 60%. In this caseMagnetic separation studies for a low grade siliceous iron ore sample

At the Iron Ore Company of Canada’s Carol Project, low-intensity magnetic separation is used as an initial cobbing step on the cyclone overflow of the ball mill discharge to remove magnetite. In any dry magnetic separator, the careful control of feed moisture is critical to avoid smaller particles sticking to larger particles (OberteufferA dry high-intensity magnetic separator is a waterless separation machine introduced to separate weakly magnetic particles that DLIMS cannot process. This technology employs a greater magnetic field strength provided by an induced or permanent magnet to separate the materials based on their magnetic susceptibility [ 21,22 ].Magnetic Separation SpringerLink
