Iron ores generally have higher grades than sulfide or gold ores, often going over 50 per cent or more. Less tailings are therefore generally produced in iron ore projects.

Bog ore is an ironrich sedimentary rock that was harvested locally from bogs and similar bodies of water. It was also found in fields and meadows that used to be bogs. Bog ore is often considerably less than 50% iron. The rest of the rock was made up of impurities that the workers had to remove. Gabbro was used as a flux;a way to purify the ore.

· Iron ( 26 Fe: (18 Ar), 4S 2, 3d 6 ) is found in the earth's crust in the form of natural ores which contains different iron oxides mixed with impurities such as Silica (SiO 2), (Al 2 O 3), CaO, and MgO, and some harmful impurities such as s, p and As, The suitability of the ore in the extraction of iron economically depends on three factors which are:

· Magnetic separation: A process in which a magnetically susceptible mineral is separated from waste by applying a strong magnetic field; ores of iron are commonly treated in this way. Magnetic survey: Technique which measures variations in the earth's magnetic field in order to define the distribution of values which may be indiive of different rock types.

Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves. The best time to collect iron ore is in the winter because the ocean is more active. Active waves separate the black, magnetic sand from lighter silica sand. This magnetic sand is an iron ore called magnetite, which when combined with carbon ...

· Removing iron by oxidation and filtration. In cases of iron levels higher than ppm, sequestration is not possible, and therefore the iron must be physically removed from the water. Removing dissolved iron is a twostage process: • The first stage is oxidising the dissolved iron and transforming it from soluble form to insoluble ferric ...

Iron is one of the world's most recycled items. It's a ferrous material with highly magnetic properties. Iron is highly sought after because it can also be used to create other metals, like steel (an iron alloy containing carbon). Scrap iron is also used to produce copper in a costeffective process, that has a low impact on the environment.

Waste plastics in blast furnace operation In several integrated steelworks in Germany and Austria as well as in Japan granulated waste plastics are used in blast furnaces to replace heavy oil or pulverized coal [1]. Besides serving as an energy source the hydrocarbons are gasified and act as reducing agents in the conversion of the iron ore.
