Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
Mar 19, 2008· Iron ore, its beneficiation and agglomeration - as required for iron and steel industry: A. Iron Ore: A naturally occurring mineral from which iron (Fe) metal is extracted in various forms viz Hot metal/ DRI etc.. B. Types of Ore: Two major varieties used for iron making are Haematite Ore ( containing Ferric Oxide - Fe2O3) and Magnetite Ore (containing Ferro-Ferric Oxide – Fe3O4).

A blast furnace charge consists of ore, fluxes and fuel. The ore part of a charge consists of iron ores and concentrates, manganese ores and various types of scrap containing iron. These ore parts are usually contained in a charge as products of a high-temperature treatment i.e. as agglomerate or pellets. Agglomerate currently
High grade iron ore less than 10% of the total reserves. ROM iron ore with Fe less than 58 – 60% discarded as waste. After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1.

Iron Ore can look like many things depending on what grade the ore is if it is a high grade such as Hematite (70.0%) or Magnetite (72.4%) then the ore will have a silver gray type but if the ore has a lower iron content like Goethite (62.9%) or Siderite (48.3%) then it is more likely to look like the type of rock that it was mined from.
Recycling : None (see Iron and Steel Scrap section).28 Кб Since international iron ore trade and production of iron ore and pig iron are key indicators of iron ore consumption, this demonstrates that ironU.S. resources are mainly low-grade taconite-type ores from the Lake Superior district that require beneficiation and agglomeration prior to commercial use.

The process of heap leaching extracts gold from ore by piling up crushed ore and applying a leaching agent to permeate through the pile, separating the gold from the ore. While this method has been used for decades with success, it has been greatly improved by the addition of an agglomeration drum to the process before the heap.
Q. sintering of iron ore 1. INTRODUCTION :- 40 to 50% iron ore becomes under size which may create pollution in the plant of the mine site. For the utilization of the variable ore, it is necessary to agglomerate the fines into the required size for charging in the blast furnace. Agglomeration is the size incensement process of the fines ore.

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...

Pellets around 4-10 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted above. The 'recipe' for successful pelletization, however, is determined through testing. Iron Ore Agglomeration Tests
The mechanisms of agglomeration and defluidization and fluidization characteristic of iron oxide particles were investigated based on the theory of surface diffusion, interface reaction, surface nano/microeffect, and phase transformation. Moreover, a mathematical model was developed to predict the high-temperature defluidization behavior by the force-balance and plastic-viscous flow mechanism ...
