Jun 23 2018 The flowsheet consists of one stage of crushing and one stage of grinding. Each of nine mill lines has one conveyor feed belt an autogenous mill with an integral trommel two slurry pumps two stages of magnetic separation and one stage of cyclone classification. Mill concentrate flows by gravity to the concentrate thickeners prior to pelletizing.
Historically the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation.
Ideally if an autogenous grinding mill could be fed only coarse competent rock and rock that is just smaller than the critical size the mill performance would improve in two ways. First since the variability in the feed size is reduced the variability in the mill feed rate would also be reduced which results in higher through-put.
5 to 50 TPH SAG Mill. Starting as small as 13 feet 4 m in diameter on 330 HP and as large as 24 14.5 m in diameter on 3300 HP the 911MPE Semi amp Fully Autogenous Mills tumble crushed ore without iron or steel grinding media. They are used when the crushed ore pieces are hard enough to
Cleveland-Cliffs owns or co-owns five operating iron ore mines in Michigan and Minnesota as well as one indefinitely idled mine in Michigan. We produce various grades of iron ore pellets including standard fluxed and DR-grade generally for use in blast furnaces around the Great Lakes as part of the steelmaking process.

SAG Mill Semi autogenous grinding SAGtechnology as an effective measure to reduce the capital investment and production cost has been widely recognized. It has been widely applied in nonmetal mineral processing ferrous metal mineral processing and nonferrous metal mineral processing and is being popularized gradually in gold processing
Nov 03 2020 The goal was to concentrate magnetite ore up to 130 th after the primary autogenous AG mill by means of magnetic drums in order to reach a higher quality of iron ore pebbles in the Concentrating Plant KA3 with a capacity of 55 - 6 Mtpy.
Jun 23 2018 Each of nine mill lines has one conveyor feed belt an autogenous mill with an integral trommel two slurry pumps two stages of magnetic separation and one stage of cyclone classification. Mill concentrate flows by gravity to the concentrate thickeners prior to pelletizing.
So we have to carry on concentrate dehydration to meet the requirements of transportation and smelting. Features 1. High Efficiency . with characteristics of large processing capacity and small floor area superfine lamination autogenous mill can save energy by more than 85. 3. Good classifying effects . Magnetic separator. CTB750 1800. 2 .
The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation. The separation step between grinding stages progressively reduces the amount of material to be ground.
Wet Energy Saving Overflow Autogenous Mill Magnetic Separation Wet Energy Saving Overflow Autogenous Mill Magnetic Separation. Wet energy-saving magnetic separator can effectively process extremely poor iron ore and improve the quality of the final iron concentrate generally used for fine-grained ferromagnetic and weak magnetic ore and iron .

Iron Ore Crushing And Grinding. Autogenous grinding mill crushing process iron ore Jul 31 2017 In the ball mill iron ore particles are broken by the grinding media acting sizes with an industrial jaw crusher then the products were sieved for so the load behavior is mainly in a crushing process and collision energy in a large scale grinding mill the largest semi autogenous grinding.
Aug 02 2019 The particles are then sent to a magnetic separator for magnetic separation and the concentrate is sent to a rotary dryer for drying and finally a dried finished concentrate is obtained. 1. Ore Grinding Ball Mill 2. Ore Classifying Spiral Classifier 3. Magnetic Separation Magnetic Separator 4. Ore Drying Rotary Dryer Process .
The pellets produced by Minnesota taconite companies generally contain between 4.0 and 7.0 percent silica. These silica levels were established initially by the concentratability of the ore that is its response to closed circuit ball mill grinding and magnetic concentration.
Various combinations of magnetic separation and flotation may be used to concentrate ores containing various iron minerals magnetite and hematite or maghemite and wide ranges of mineral grain sizes. Flotation is also often used as a final polishing operation on magnetic concentrates.
Inside the ball mill the crushed iron ore will grind the ore to about 0.2 mm with 3-inch steel balls. 3.This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore -0.074 mm going to froth flotation cells for recovery of iron.
Bridge type bucket-wheel blending reclaimers are an excellent option for blending and reclaiming bulk materials like coal concentrate and fines in raw material stockyard for fields like iron amp steel industry. The reclaimer has the features including good blending effect large reclaiming capacity and high productivity. NHI has supplied nearly .
Advantages. 1. In crushing it adopts traditional two-stage and a closed circuit system for ideal fineness. Besides jaw crushers have large crushing capacity. 2. In grinding and classification with characteristics of large processing capacity and small floor area superfine lamination autogenous mill can save energy by more than 85. 3.
