A process for the direct recovery of tin values, as organo hydrocarbyl tin compounds, from reduced but unrefined tin ores and ore slags is described, wherein the ore or slag is reacted directly with a hydrocarbyl halide to form an organo hydrocarbyl tin compound which can then easily be separated from the tindepleted ore or slag residue. EPA1 Extraction of tin from its ores Google
Extraction of Iron. Chemistry of the blast furnace. Hot air is blasted into the furnace causing coke (carbon) to burn rapidly producing carbon dioxide and raising the temperature to 2000 #176;C. carbon + oxygen carbon dioxide + heat. C (s) + O 2(g) CO 2(g) The carbon dioxide then reacts with hot carbon to form carbon monoxide. carbon dioxide + carbon carbon monoxide. CO 2 (g) + C (s) 2CO (g
What is a word equation for the extraction of tin from tin oxide using carbon? Asked by Wiki User. Be the first to answer! 0 1 2. This means that the formula for carbon monoxide is CO.

06/06/2017#0183;#32;In extracting metals, carbon in the form of coke is used. 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.
Extraction of Metals. Extraction of Iron.. Chemistry of the blast furnace.. Hot air is blasted into the furnace causing coke (carbon) to burn rapidly producing carbon dioxide and raising the temperature to 2000 #176;C.. carbon + oxygen carbon dioxide + heat. C (s) + O 2(g) CO 2(g) . The carbon dioxide then
Whereas for zinc it is extracted from its ore chemically by reduction using carbon. When an ore is reduced you are taking the oxygen out of the metal, this is because carbon can only take the
#0183;#32;The most common ore of tin is cassiterite, which is stannic oxide, or tin (IV) oxide. with the formula SnO2. The word equation for the reduction of tin with carbon is: tin oxide + carbon (+ heat) tin + carbon dioxide. The carbon dioxide is given off as a gas and the melted tin
The method used to extract metals depends on the reactivity of the metal. Metals are used for a variety of purposes. An alloy is a mixture of a metal and another element.
The method. Three substances are needed to enable to extraction of iron from its ore. The combined mixture is called the charge:. Iron ore, haematite often contains sand with iron oxide, Fe 2 O 3.. Limestone (calcium carbonate).. Coke mainly carbon.. The charge is placed a giant chimney called a blast furnace. The blast furnace is around 30 metres high and lined with fireproof bricks.
Describe the use of carbon in the extraction of some metals from their ores. Metals below carbon in the reactivity series can be extracted using carbon. Carbon reduces the metal oxides that are extracted when heated. Example: lead (II) oxide + carbon (coke/coal) gt; lead + carbon monoxide. The carbon in the form of coke (which is coal from which impurities have been removed
Processes for the separation of carbon monoxide from feed gas streams polluted with nitrogen are disclosed, in which the feed gas streams, which preferably include hydrogen and methane therein, are supplied to a distillation column, and including the steps of distilling the feed gas stream to produce as the sump product a first carbon monoxide stream of substantially pure liquid carbon
Carbon monoxide. Carbon monoxide is usually treated as if it was a neutral oxide, but in fact it is very, very slightly acidic. It doesn''t react with water, but it will react with hot concentrated sodium hydroxide solution to give a solution of sodium methanoate. The fact that the carbon monoxide reacts with the basic hydroxide ion shows that it must be acidic. Carbon and silicon dioxides

#0183;#32;The carbon displaces the metal from the compound, and removes the oxygen from the oxide. This leaves the metal. The table summarises the extraction methods used for different metals.
Carbon monoxide (CO) is a colorless, odorless, and tasteless flammable gas that is slightly less dense than is toxic to animals that use hemoglobin as an oxygen carrier (both invertebrate and vertebrate) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions.
Carbon monoxide Silicon monoxide Germanium(II) oxide Lead(II) oxide : Related tin oxides. Tin dioxide: Except where otherwise noted, data are given for materials in their standard state (at 25 #176;C [77 #176;F], 100 kPa). what is ?) Infobox references: Tin(II) oxide (stannous oxide) is a compound with the formula SnO. It is composed of tin and oxygen where tin has the oxidation state of +2. There
The metal in the oxide is then reduced by carbon monoxide and the product of the reaction will be metal and carbon dioxide. metal oxide + carbon monoxide metal + carbon dioxide ** The chemistry of metal extraction is very complicated, so when we simplify the reactions it is not really possible to be accurate about what the exact nature of the reactants and products will be.
#0183;#32;Less reactive metals than carbon can be extracted from their oxides by heating with carbon. In general: metal oxide + carbon metal + carbon dioxide. This works for zinc, iron, tin
Gaseous reduction of tin ores has been studied periodically over many years. The use of hydrogen or carbon monoxide gases has been most frequently proposed but other reducing gases such as commercial gases containing hydrogen and carbon monoxide
