2.4. Beneficiation methods. Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.
Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.
The beneficiation process of magnetite mainly includes 4 stages. Once you have discovered or mined magnetite, you can extract iron concentrates through the following process. Magnetite crushing and screening …

Beneficiation Equipment Required for Hematite Gravity Separation Process. 1. Spiral Chute. The spiral chute is based on the different specific gravity of the different iron minerals. After the slurry is fed, the minerals are settled according to the specific gravity by the combined action of water flow, mineral gravity, and the friction …
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.
ematite separation process is suitable for complex structure hematite such as hematite and impurities with uneven distribution of particle size, ore with large content of fine particle, ore with small amount of magnetite and the …
