MoreVale has inaugurated its new dry pilot plant for processing iron ore in Minas Gerais, Brazil, as it continues to reduce its use of water in ore and waste processing. The Brazilian , known as FDMS (Fines Dry Magnetic Separation), is unique and has been developed by New Steel – a company Vale acquired in late 2018 .

MoreMar 19, 2021 Fines dry magnetic separation promises a new alternative. Even before the 2019 disaster, Vale was busy looking for alternatives to wet magnetic separation. The eventual breakthrough the company made came too late for the victims in Minas Gerais, but it could transform life for other miners and the local environment.

MoreApr 03, 2014 DSO, gravity separation, Iron ore, iron ore beneficiation, magnetic separation, Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite).

MoreMagnetic separation process (iron ore beneficiation plant or iron ore processing plant) is made up of jaw crusher, ball mill, spiral classifier, magnetic separator, concentrator and dryer, etc. Since this magnetic separation process is advanced, utilization rate of minerals can reach 90%. Water and power consumption is little.
