Iron was likely originally discovered and extracted as a result of wood burning on top of ironcontaining ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (presentday Iraq) between 2700 and 3000 BCE.

Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press.

In a bloomery, the fire doesn''t get hot enough to melt the iron completely. Instead, the iron heats up into a spongy mass containing iron and silicates from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silicates into the iron metal to create wrought iron is hardy and easy to work, making it perfect for creating tools.

Reduction of Metals (Extraction from Ore) There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. Extraction using carbon. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain

When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix. The metal in the nails reacts with the metals in the sulfides reducing the metals to their metallic state. This is handy when processing silver containing minerals to convert them to silver metal. The addition of scrap iron to smelt mixes is a useful technique to smallscale operators experimenting

Iron ore is not pure iron oxide it also contains an assortment of rocky material that would not melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the

Concentration removes the water and other volatile impurities such as sulfur and carbonates. This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction

process of separating the iron from the noniron material. The magnetic iron ore is then laundered in two slurry surge tanks while the nonmagnetics (silica/sand) go to the tailings disposal area. Most of the material continues to be finely ground in one of five secondary ball mills, which are powered by electric motors ranging from 2,500 hp to 4,000 hp and are charged with 11/2" chrome

CONVERSION OF CONCENTRATED ORE INTO METAL OXIDE. After concentration of ores, the sulphide or carbonate ores of some metals are converted into metal oxides because it is easier to obtain metals from their metal oxides as compared to metal sulphides or metal carbonates. The sulphide ores of metals can be converted into their oxides by roasting while the carbonate ores of metals can be converted

The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique. Smelting methods range from the basic to the hightech, and are applied to a variety of materials, including aluminum, iron and copper.

From iron ore to steel Steel is derived from iron. However, this metal does not exist as a pure element in nature but only in chemical compounds, for the most part in an oxygenated form. This rocklike or earthy substance is called iron ore. • Iron Ore represents – according to the mining sector – an iron content of between 30 to 70 percent of total weight. It exists in various

However, some lateritic bauxite ores are readily soluble in caustic, making it possible for them to be leached, or "digested," at atmospheric pressure.
