TRANSITION METALS chemical reactions physical properties

The physical properties of Transition Metals like density, melting points, boiling points, strength are described and discussed along with a description of the important transition metal chemical properties of e.g. titanium, vanadium, manganese, iron, cobalt, nickel, copper and zinc. There are also sections on how metals can be improved to increase their usefulness e.g. alloys and they are

Midrex Process for Direct Reduction of Iron Ore

Midrex Process for Direct Reduction of Iron Ore

Midrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas.

Zinc oxide

Zinc oxide

Zinc oxide is an inorganic compound with the formula Zn O.ZnO is a white powder that is insoluble in water, and it is widely used as an additive in numerous materials and products including rubbers, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, and first aid tapes.

Oxide

Oxide

In dry oxygen, iron readily forms iron(II) oxide, but the formation of the hydrated ferric oxides, Fe 2 O 3x (OH) 2x, that mainly comprise rust, typically requires oxygen and water. Free oxygen production by photosynthetic bacteria some 3.5 billion years ago precipitated iron out of solution in the oceans as Fe 2 O 3 in the economically important iron ore hematite.

Pegmatites and aplites Their genetic and applied ore geology

Definition The term ore is defined in the current study to describe a concentration of non metallic, e.g., feldspar, or metallic minerals, e.g. spodumene, in pegmatitic rocks irrespective of its structure and position in the deposit which was or is currently mined for a profit.

Aluminium   Element information, properties and uses

Aluminium Element information, properties and uses

The analysis of a curious metal ornament found in the tomb of Chou Chu, a military leader in 3 rd century China, turned out to be 85% aluminium. How it was produced remains a mystery. By the end of the 1700s, aluminium oxide was known to contain a metal, but it defeated all attempts to extract it.

Metal Profile Iron Properties and Characteristics

Metal Profile Iron Properties and Characteristics

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