Laterite with Fe2O3 Al2O3ratio more than 1 and SiO2 Fe2O3 ratio less than 1.33 is termed as ferruginous laterite USES The industrial use of laterite is in the cement industry. It is used as an additive for lowering the clinkerization temperature and supplementing aluminous and iron contents required in the manufacture of cement.

Iron ore definition of Iron ore and synonyms of Iron ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey bright yellow deep purple to rusty red. The iron itself is usually found in the form of magnetite Fe 3 O 4 hematite Fe 2 O 3 goethite FeO OH limonite FeO OH .n H 2 O or siderite FeCO 3 .Ores carrying very high
It contains the iron oxide minerals goethite HFeO 2 lepidocrocite FeO OH and hematite Fe 2 O 3. It also contains titanium oxides and hydrated oxides of aluminum the most common and abundant of which is gibbsite Al 2 O 3 3H 2 O. The aluminum rich representative of laterite is bauxite. Laterite is frequently pisolitic pealike .

Phosphate removal from water by naturally occurring shale
Jan 01 2019 Indeed the shale contained the lowest quantity of iron and the lowest proportion of Fe in iron oxides i.e. 31 compared with 97 and 100 observed for laterite and sandstone respectively. Iron oxide particles in particular those with low crystal size are well known to develop strong bonding sites for surface complexation by phosphate species.
Investigation of Affecting Parameters on Heap Leaching
that there are high correlation between copper and iron recoveries. Copper recovery changed from 25.5 to 58.9 while iron recovery changed from 4.7 to 15.2 . Acid consumption were achieved between 18 to 54 kg per ton of ore. Acid solution concentration and irrigation flow rate are the most important parameters on the copper and iron recoveries.

Aug 07 2021 For every 1 ton of iron ore concentrate produced approximately 2.5–3.0 tons of iron ore tailings will be discharged. Based on the rule of thumb of 50 Mt/y per car dumper reclaimer and ship loader the new production would require approximately ten new car dumpers reclaimers and ship loaders. 31 Iron oxides and oxyhydroxides are
NICKEL RECOVERY FROM ELECTRIC ARC FURNACE SLAG BY
Arc Furnace EAF . Because iron in the steel slags is normally encountered in the form of steel 7–10 iron oxide and iron bearing minerals the recovery of iron is achieved by crushing or grinding screening and magnetic separation 17 . Similarly to iron slags steel slags can also be used in other applications. Alloy steel slags.
