06/06/2017· Carbon is widely used in the extraction of zinc, iron, tin and lead for a number of reasons: a First of all, carbon is more reactive than zinc, iron, tin and lead. Therefore, carbon can easily reduce the oxide of these metals. b Furthermore, carbon is cheap and easily available. c The carbon dioxide gas produced is not poisonous and thus can be released
Extraction of Iron Iron is extracted from its ore, that is hematite Fe 2 O 3 andite Fe 3 O 4 through reduction by carbon in the form of carbon in a blast furnace. The mixture of iron ore, carbon, and limestone is entered into a blast furnace through the top of the furnace. Hot air is then put in through the lower part of the furnace
However, the tin concentrate grade of 40 is required, meaning the enrichment of hundreds or thousands times. Targeting at the refractory tin ore, low grade tin concentrate is obtained and it has to be further extracted by special metallurgy process. Reduction smelting is the dominant process to extract tin metal from tin concentrate. Metalcess
Extraction of Tin/ Stannum. Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8 7g/cm 3, density larger than most of gangue. Therefore, 90 of tin concentrate is mainly obtained from cassiterite through gravity separation.

Six mark questions are extended open response questions. These require longer answers than the structured questions. It is wise to plan your answer rather than rushing straight into it,
20/01/1987· In the usual temperature range at which tin refining is carried out, the solid in equilibrium with liquid tin is FeSn 2, the so called hard head, containing 19 iron by weight. Present methods of removing iron from tin depend on the crystallisation of FeSn 2 from liquid tin at low temperatures.
Tin ore continued to be mined but not as much as in the past glorious years of the 70s and 80s when Malaysia was the worlds largest tin ore producer. High grade deposits have inevitably been exhausted following decades of tin mining. Competition from other economic sectors, such as agriculture, plantations, property and industrial developments, over land use have made them
Iron and copper pyrites are converted into their oxides and sulphates Washing: This ore is then washed with hot water to dissolve out copper sulphate and iron sulphate. The lighter ferric oxide is washed off while the concentrated tin stone sinks to the bottom. It is called black tin.
5 a In the extraction of tin from tin oxide, tin oxide is heated with carbon. SnO 2 + C : Sn + COplete the sentence by putting a cross in the box next to your answer. When the tin oxide reacts with carbon to form the products 1 A tin is oxidised B tin oxide is reduced C carbon is reduced D carbon dioxide is oxidised

Therefore, 90 of tin concentrate is mainly obtained from cassiterite through gravity separation.
The principal difficulty in the Pyrometallurgical technique for gaining tin metal is the separation of tin from iron due to the high temperature of smelting. The smelting conditions should be such that the tin oxide is reduced to the metallic state while iron oxide is reduced to lower oxide the ferrous oxide and passes into the slag.

Extraction of Metals. The History of Metals. Metals have been used by people for many thousands of years. Gold and silver, found as native metal, were used both as jewellery and as a status symbol nothing new there. These metals were known in the Stone Age but gold and silver are too soft to be used as tools. The first really useful metal to be discovered was bronze. This
