The beneficiation of iron ore is relatively more effective, when RAF operation applied along with magnetic concentration. Data indicate that it enhance the Fe% value from 29% of Fe to 50 % Fe. The magnetic operation removes the slimes, which beneficiate the iron ore of 65.22% of Fe whereas recovery percentage has been calculated 78.42% (Zhu ...
Abstract A new process is developed for metallurgical beneficiation of iron laterite nickel-containing (limonite) ores with the formation of a metallic nickel–cobalt concentrate. This process includes reducing roasting of the ores with sulfur-containing additions in the temperature range 1100–1200°C, the fragmentation of the roasting product, and the magnetic separation of …

Among them, limonite, as a typical refractory iron ore, has the characteristics of easy siltification and poor sorting indicators. However, due to its abundant reserves, it is a favorable backing to solve the shortage of iron resources. The common limonite beneficiation method mainly includes a single sorting process and a joint sorting process.
