The iron ore resources are featured with lean ore, less rich ore, associated ore and complex ore composition. There are a variety of iron ores in nature, mainly including magnetite, haematite, limonite, siderite, so the beneficiation of iron ore needs a.
Oct 20, 2015 In the present paper, an attempt has been made to beneficiate iron ore tailings by selective flocculation using guar gum and starch as flocculants along with sodium hexametaphosphate (SHMP) as the dispersant. The mineralogical studies carried out initially indicated the presence of hematite and goethite as major iron bearing mineral phases along with quartz and kaolinite as major gangue.
Before iron ore can be sintered, it must be granulated to improve sinter bed permeability. Research into granulation The iron ore industry has been working on blend design and ore design for some time. One component that will as gangue type quartz tends to occur as discrete, relatively coarse particles.
High alumina and silica content in the iron ore affects coke rate, reducibility, and productivity in a blast furnace. Iron ore is being beneficiated all around the world to meet the quality requirement of iron and steel industries. Choosing a beneficiation treatment depends on the nature of the gangue present and its association with the ore structure.
