beneficiation reduce the gangue

a novel dry beneficiation technology for pyrite recovery

a dry beneficiation technology was proposed for pyrite recovery to reduce gangue accumulation. experiments was conducted for pyrite recovery from 6 to 50 mm and <6 mm gangue sample. efficiency of pyrite recovery was analyzed by the advanced measurement facilities.

beneficiation of iron ores free essays

these ores ca n be directly used in the production of iron and steel. all other ores need benefaction and certain processing before they are used in t he production of iron and steel. low grade iron ores cannot be used as such for the production of iron and sst eel and need to be upgraded to reduce its gangue content and increase its fee content.

how is iron ore beneficiation done?

how iron ore beneficiation is done depends heavily on the characteristics of the ore. in particular it depends on what iron-bearing minerals are present what gangue minerals they are combined with and the particle size that they must be reduced to in order to break the iron-bearing minerals free of the gangue.
