11.23 Taconite Ore Processing

Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1. Liberation is the first step inFirst step in the process is crushing and grinding coupled with wet or dry size-classification of run of mine (ROM) ore. This is required to prepare feed for beneficiation of ore. Iron ore processing operating practices vary depending upon the the quality of iron ore deposit.Iron ore beneficiation: an overview ScienceDirect

Many ores contain relatively low concentrations of the desired metal; for example, copper ores that contain even 1% Cu by mass are considered commercially useful. After an ore has been mined, the first step in processing is usually to crush it because the rate of chemical reactions increases dramatically with increased surface area.Iron ores are the primary source for iron melting. Almost all of the iron ores are transformed into steel, cast iron and iron based alloys. Cast iron and steel are the fundaments of modern industries. The processing of iron products goes in a few stages. Usually it is mining, mineral processing, agglomeration, casting, depuration. Each stepEffective Processing of the Iron Ores

Iron ore sintering ScienceDirect

Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described to identify the key steps of the process, that is, granulation and thermal densification. Discussion is then focused on the effect of the chemical, physical, andSteelmaking. Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produceSteelmaking

Iron Ore Processing, General

Iron Ore Processing, General 1 Introduction Iron is the world’s most commonly used metal–steel, of which iron ore is the key ingredient, representing almost 95% of all metal used per year. It is used primarily in structural engineering applications and in maritime purposes, automobiles, and general industrial applications (machinery).149. For an iron ore of 10-30 mm size, with an average mean size of 18 mm, the angle of repose is around 33-35°. For coke of 27-75 mm size, with an average size of 45 mm, the same is around 35-38°. Similarly the angle of repose for sinter is in the range of 31--34° and for pellets it is around 26-28°.Iron making PPT SlideShare
