OUTOTEC DIRECT REDUCTION AND SMELTING REDUCTION

The standard SL/RN process has been used for over 40 years to produce direct reduced iron (DRI) from lump ores or iron ore pellets. However, with the decreasing availa-bility of lump ores the ability to process fine-grained ores and concentrates is becoming increasingly important. The SL/RN process cannot be used to treat iron ore concen-

Froth Flotation of Iron Ores - sapub

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

How iron is made - material, manufacture, …

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon ...

Extraction of Chromium from Chromite Ore

Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1. Refractory-grade chromite ores contained a minimum of 20 pct Al2O3 and more than 60 pct Al2O3 plus Cr2O3. Primary chromium needs for all uses in the United States by the year 2000 are estimated to be nearly three times its present annual consumption (400,000 short tons), and ...
