Iron Ore Mill Scale Purifiion

Mill scale consists of oxides of iron, above all, but also the metal alloys that are included in the steel of which the mill scale is formed. Chemically, the mill scale can be compared with iron ore and can frequently be used in similar applications, e.g. as a raw material on production of pig iron, ferrous alloys and cement.

D.R.I. Fines. Direct-reduced iron (DRI), also called sponge iron is produced from the direct reduction of iron ore (in the form of lumps, pellets or fines) to iron by a reducing gas produced from natural gas or coal. Few ores are suitable for direct reduction. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high …

According to Trading Economics, the global iron ore price has collapsed from a peak of $229.2 per tonne on 12 May this year to just $115 per tonne on 19 October. As key industrial producers, such as China and Brazil, have increased production, following disruptions earlier during the Covid-19 period, the value of iron has almost halved.

The main feedstock on this route remains BF-grade iron pellet, while scrap can again be added in the steelmaking plant. One noteworthy advantage is the ability to add iron bearing wastes (up to 3 to 5% of overall charge), such as BF and BOF dust, mill scale and others within the smelter.

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.

These plants use iron carbide, an iron ore that contains 6% carbon rather than 1.5-1.8% of regular iron ore . The additional carbon ignites in the presence of oxygen and contributes heat to the iron melting process, reducing energy requirements (Ritt, 1996).

Strong demand for steel is driving the price of iron ore to all-time highs Iron ore prices continued to hit record highs during the second quarter of 2021, reaching US$238 a tonne in early May. The average spot price for 62% Fe iron ore fines at Chinese ports in May was an increase of 37%

The China Iron and Steel Association (CISA) reported that crude steel output across major mills in China averaged 2.32 million mt per day in the second ten days of April, up 2.21% from early April and up 19.1% from the same period a year ago.

The typical iron oxide mix for Corex is pellets, even a stabile operation by use of lump ore fraction up to 80% is possible. The iron ore mix depends on the price of lump ore available. In addition, no sinter - and therefore no sinter plant - is necessary for optimal operation.
