Iron ore - Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines.

Creating Steel | HowStuffWorks

The advantage of steel over iron is greatly improved strength. The open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface.

Iron Ore Statistics and Information - USGS

Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.

Iron Ore | The Canadian Encyclopedia

Therefore, these mines crush and grind the ore, then use gravitational and magnetic concentration methods to produce concentrates with an iron content of about 65%. Depending on grain size, the concentrate is then shipped as is, or agglomerated into balls about a centimetre in diameter and fired to produce hard iron ore pellets.

Production and Distribution of Iron Ore in India

This fact speaks volumes of high concentration of iron ore reserves and their lopsided distribution in the country. 1. Karnataka: ADVERTISEMENTS: Karnataka is the largest producer and accounts for nearly one-fourth of the total iron ore produced in India. In Karnataka production of iron ore has increased by about three times since 1980.

Gold extraction - Wikipedia

Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting, and pressure oxidation prior to cyanidation.

First ground to a fine powder, the ore is next concentrated using magnetic separation and flotation to 60 to 65 % iron, then rolled into 3/8" dia pellets that are purplish-grey when they emerge, steaming, from the plants. Turning low-grade crude ore into high-grade concentrate requires a means of separating the iron particles from the waste rock.
