Iron ore deposits of india PPT SlideShare

9 2 Sedimentary iron ore deposits of siderite and limonitic composition It is also known as Bog iron deposit These ores of siderite and limonitic compositions are found associated with the iron stone shales of lower Gondwana age The iron minerals are accumulated as irregular bodies in stream beds and typically at the bottom levels of bogs and marshes

Phenomena in the froth phase of flotation — A review

Froth flotation was commercially introduced early in the 20th century Now almost 100 years later it is the most important and widely used separating method for its application to mineral flotation the ore is first ground in water to a certain size to produce a suspension which is then subjected to vigorous mixing in a suitable vessel

Iron ore is concentrated by Toppr

Froth floatation D Magnetic treatment Open in App Solution Verified by Toppr Correct option is D Magnetic treatment As Iron ore contains magnetic part $$ Fe 2O 3 $$ and non magnetic part $$ gangue $$ Hence Magnetic Separation is used for concentration of Iron Ore

Metallurgy of copper PPT SlideShare

CONCENTRATION • Finely crushed ore is concentrated by FROTH FLOATATION PROCESS • Crushed ore is suspended in water containing a little amount of pine oil • A blast of air is passed through the suspension • The particles mix with the oil and float as a froth which is skimmed • The gangue sinks to the bottom

PDF An overview of the beneficiation of iron ores via

Flotation is the most effective solution both technologically and economically when upgrading iron concentrates Research regarding iron ore flotation began in 1931 demonstrating that reverse

Froth Flotation and its Application to Concentration of Low Grade Iron

Froth flotation is a process used to separate minerals suspended in liquids by attaching them to gas bubbles to provide selective levitation of the solid particles It is most extensively used process for the separation of chemi cally similar minerals and to concentrate ores for econo mical smelting Flotation is a selective process and can be used to achieve separation from complex

Froth Flotation ppt download

What is Flotation Flotation is a mineral separation process which takes place in water mineral slurry In this process by attaching mineral particles to air bubbles to provide selective levitation of them 1 The surfaces of selected minerals are made hydrophobic water repellent by conditioning with selective reagents 2 The hydrophobic particles become attached to air

Extraction Of Iron PPT SlideShare

6 Occurrence of Iron Iron is very reactive and is found in nature in form of its oxides carbonates and sulphates The main ores are i Haematite Fe2O3 ii Magnetite Fe3O4 iii Iron Pyrites FeS2 o The main iron ore is Haematite iron III oxide Fe2O3 o The iron ore contains impurities mainly silica silicon dioxide o Since iron is below carbon in the reactivity

Investigation of Adsorption Mechanism of Reagents Surfactants System

Iron ore flotation started with direct flotation of iron oxides using selected anionic collectors such as petroleum sulphonates fatty acids and hydroxamates Direct flotation route was incorporated in the industries in the 1950s in Humboldt Mine USA 1954 Republic mines USA 1956 Groveland mine USA and Anshan Iron and Steel corporation
