Feb 24, 2015· A significant fraction of iron ore used in steel production comes from magnetite deposits. Magnetite iron ore requires significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot of energy. This article investigates ecoefficient alternatives for the process design for magnetite iron ore.
Jul 11, 2016· Ore Grinding Mills are used for the fine grinding as the last step in the reduction of an ore prior to concentration (gravity or flotation) or varies, depending upon the type of ore and the amount of reduction required. In addition, some of the older properties continue with methods that perhaps are not considered the best in light of recent improvements but that cannot be ...
Processes for Beneficiation of Iron Ores Iron is an abundant element in the earth''s crust averaging from 2 % to 3 % in sedimentary rocks to % in basalt and gabbro. Because iron is present in many areas, it is of relatively low value and thus a deposit must have a high percentage of metal to be considered ore .

screens have been used in iron ore since the 1950''s processing all types of iron ore. From removing fine impurities in Direct Shipping Ore sinter products to scalping relatively coarse (+53 to 75 µm) middlings and size control in pellet concentrates.
Processing of Magnetite Iron Ores Comparing Grinding Options Although the majority of current steel production is supported by iron ore sourced from high grade haemetite deposits, the longterm growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed.
Iron ore grinding and classification. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits are much finergrained and therefore require significant grinding to liberate the magnetite from its silicate matrix. Various magnetite ore grinding flowsheets have been implemented in the past, including

achieving coarse grinding in a ball mill is the function of a number of parameters: 1, The mill L/D ratio must be low, for example diam. 9ft x 10ft long. 2, The mill must be of grate discharge configuration as opposed to overflow discharge. This will ensure a steep hydraulic gradient in the mill for rapid passage of the ore through the mill.
