In this study, suspension magnetization roasting (SMR) and low-intensity magnetic separation (LIMS) were used to process ferromanganese ore. Under the optimum conditions, magnetic products with an iron grade of 69.66% at an iron recovery of 98.17% and nonmagnetic products with a manganese grade of 51.60% at a manganese …

Abstract. 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, so low-intensity magnetic separators are used to upgrade magnetite ores. On the other hand, because oxidized …

If your DMS concentrate contains weakly paramagnetic and diamagnetic minerals (e.g, diamonds), a three-stage tiered magnetic separation process is ideal for sorting. Stage 1: A weak magnet and a high-belt speed – scalping process removes ferromagnetic material. Stage 2: A medium-strength magnet and/or slower belt speed – …

Magnetic Separation Principle. Magnetic separation is a beneficiation method that uses the magnetic difference between minerals in a non-uniform magnetic field to separate different minerals. Magnetic separation is the most commonly used beneficiation method for ferrous metal ore such as iron ore. It is divided into weak …

The principle of the process consists of converting the iron bearing minerals into the magnetic state so that magnetic separation can be employed to concentrate iron from the ore [2]. The gas used for reduction purposes may be either pure hydrogen, carbon monoxide or industrial gases like blast furnace gas, coke oven gas and producer gas.

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.
