Iron Ore Beneficiation Testwork | SRK Consulting
Ores can often respond to gravity and/or magnetic separation. However, due to the presence of loweriron content, iron minerals such as goethite, mass yields and recoveries to high grade concentrates can be low. Tradeoffs are then required between recovery and product quality (iron grade and penalty element content).

Iron ore pricing explained
· Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use in the blast furnace. Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium.

HBI production | International Iron Metallics Association
The schematic represents the HBI briquetting process. Direct Reduced Iron is discharged hot from the reduction furnace and screwfed into the nip between two counter rotating rollers. Pockets in the synchronously rotating rollers form the briquettes. This process occurs at high temperatures (typically approx. 700 °C) and high pressing forces.

Direct reduced iron process
· The process gases carbon monoxide ( C O) and hydrogen ( H 2) are blown into the furnace at temperatures of approx. 1000 °C and flow through the iron ores. The reduction of iron oxides takes place according to the following chemical equations: (1) F e 2 O 3 + 3 C O → 2 F e + 3 C O 2 (2) F e 2 O 3 + 3 H 2 → 2 F e + 3 H 2 O

iron processing
Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed ironbearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; magnetite .

Iron Deficiency in Plants How to Add Iron to Garden Soil
Iron is also important in plant respiration, which is when plants use sugar (from photosynthesis) and oxygen to produce energy for growth. In addition, iron plays a role in the transport of nutrients, such as oxygen, throughout a plant's tissues. In short, iron is vital to the overall health and development of plants.

Visiting Germany's Abandoned Volklinger Ironworks
· The blast furnaces at Volklinger Ironworks turned raw ore into pig iron using high heat, coke, and limestone to reduce oxygen and sulfur — producing a "slag" of impurities that floats to the top. Then the pure molten iron can be drained out of the bottom of the furnace and loaded into special rail cars that take it to a nearby steel mill.
