Decomposition – Definition, Types and Reaction Examples
Iron sulphate which is of green colour is decomposed to form a brown-coloured ferric oxide and gases like sulphur dioxide and sulphur xide gases are released. Lead nitrate on thermal decomposition gives lead monoxide which is yellow. With this brown gas nitrogen dioxide and oxygen gas are released.

Pig Iron Production
For general information about merchant pig iron, please visit the pig iron page. Modern blast furnaces produce more than 10,000 tonnes per day. Blast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases.

Sulfur xide
Sulfur xide (alternative spelling sulphur xide, also known as nisso sulfan) is the chemical compound with the formula SO 3.It has been described as "unquestionably the most important economically" sulfur oxide. It is prepared on an industrial scale as a precursor to sulfuric acid.. Sulfur xide exists in several forms - gaseous monomer, crystalline trimer, and solid polymer.

Carbon
This exothermic reaction is used in the iron and steel industry to smelt iron and to control the carbon content of steel: Fe 3 O 4 + 4 C (s) + 2 O 2 → 3 Fe (s) + 4 CO 2 (g). Carbon reacts with sulfur to form carbon disulfide, and it reacts with steam in the coal-gas reaction used in coal gasification: C (s) + H 2 O (g) → CO (g) + H 2(g).

Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the …

Ore
Ore is a class of materials found naturally on planets. It can be extracted through mining and refined into bars using furnaces such as primitive furnace, industrial furnace, and atomic furnace.Bars are a main component of crafting weapons, armor, and furniture. Ore is distributed in proportional layers throughout planets, meaning smaller planets will have less ground to dig …

Mount Isa Mines
Even after the first ore had been mined and processed, the Mount Isa operations struggled. The smelter proved inadequate and required a third blast furnace and additional sintering machines. The recovery of valuable minerals in the concentrator was less than expected, and the metal prices were depressed by the Great Depression of the 1930s. The poor recoveries were found …

Non-stoichiometric compound
The monosulfides of the transition metals are often nonstoichiometric. Best known perhaps is nominally iron(II) sulfide (the mineral pyrrhotite) with a composition Fe 1-x S (x = 0 to 0.2). The rare stoichiometric FeS endmember is known as the mineral troilite.Pyrrhotite is remarkable in that it has numerous polytypes, i.e. crystalline forms differing in symmetry (monoclinic or …
