Tinned iron vessels appeared in central Europe, in the 1300s. Thin sheets of iron coated with tin, called tinplate, became available in England during the mid-1600s and were used to make metal containers. In 1810, Pierre Durand of France patented a method of preserving food in sealed tinplate cans.

The extraction of copper was essential to the discovery of other metals, such as iron and bronze. As early as 3000 BC, Sumerians and Egyptians were using copper alloyed with tin to create bronze. The metal was a vital resource for both Greeks and Romans.
A metal, which is lower than iron in the electrochemical series is connected to the iron. ? The other metal corrodes first in preference to the iron. ? This method is also known as 'sacrificial protection'. ? This method is used to prevent corrosion of ships.
The flowsheet below Explains the Extraction of Tin Ore as shown by a study adapted to the concentration of a lode tin deposit. Cassiterite (SnO2) is very friable and special considerations to crushing and grinding of the ore are necessary to avoid an excessive production of fines.
Metallic tin or stannous sulphate or nitrate can be substituted for stannous chloride. Another technical method for its preparation is to heat "pink salt," SnCl 4,2NH 4 Cl, with tin-foil and water until solution of the tin is complete, dilute with water, and pour the solution into a dilute aqueous gold solution. It is also produced by dissolving gold-tin alloys in nitric acid.
The melting temperature of three metals, iron, copper, and tin, is at the heart of the Hittite discovery. Iron has a melting point of 1535 degrees C (about 2795 degrees F), copper melts at 1083 degrees C (about 1972 degrees F), and tin melts at 231.97 degrees C (about 422 F).

Bronze is a combination of copper and tin, usually roughly eight or nine parts copper to one part tin. In some cases additional elements were added as well. As noted, copper itself is quite a soft metal, and only marginally useful for tools. So, for that matter is tin.

Calcium occurs before iron in the activity series so calcium is the more active metal. Infer the relative stability of the compounds each metal will form. More active metals form more stable compounds than less active metals. Calcium will form more stable compounds than iron.
Because of this, carbon is used in the extraction of zinc, iron, and lead. This is a relatively cheap way to extract metals because carbon is readily available from coal. The extraction of metals from ores can cause environmental problems.

extraction of iron The first really useful metallic alloy to be discovered was bronze in the Bronze Age. Bronze is not an element (like gold and silver) but an alloy (metal mixture) of copper and tin.
Most tin is found in alluvial deposits, riverbeds, and former riverbeds, as a result of erosion of ore bodies containing the metal. China and Indonesia are currently the world's largest producers. Tin is smelted at temperatures of up to 2500°F (1370°C) with carbon to produce low purity tin and CO 2 gas. It is then refined to high purity (>99%) tin metal through boiling, liquation or electrolytic methods.
Since iron did not fully melt at the temperatures ancient metalworkers were able to produce, iron was normally worked by other methods (outside of China), but lead, copper, and bronze were usually cast, and molds have been found from metalworking cultures around the world.
Jan 20, 1987· The preferred organic catalyst for the tin extraction is an `onium` compound as defined in GB No. 1,156,646 (U.S. Pat. No. 3,415,857) and is normally present in an amount of from 0.1 to 0.6, preferably 0.2 to 0.5 moles per gram-atom of tin in the tin ore concentrate.
In the Iron Age bronze continued to be used for ornaments though not for tools and weapons, so tin extraction seems to have continued. An ingot from Castle Dore is probably of Iron Age date. An ingot from Castle Dore is probably of Iron Age date.

Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something. With titanium, however, you make it one batch at a time.
However, large amounts of lead and up to 10 mg of tungsten will not interfere if the precipitates are removed by filtration before the extraction step. More than 100 mg of copper may interfere with the extraction of tin, by precipitating as cuprous iodide. Iron(III) is reduced to iron(II) with ascorbic acid before the extraction step.
Arsenic, antimony and tin are then removed by skimming as sodium arsenate, antimonate and stannate. The sodium antimonate is separated from these by lixiviation, and is reduced to antimony by treatment with carbonaceous material.
Tin. Tin is a soft, pliable, silvery-white metal. Tin is not easily oxidized and resists corrosion because it is protected by an oxide film. Tin resists corrosion from distilled sea and soft tap water, and can be attacked by strong acids, alkalis and acid salts.

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.
The Hittites appear to have produced an iron which could be reheated and worked, suggesting that their product was a form of wrought iron or some version similar to carbon steel. Charcoal was used as the reducing agent, layered with the iron ore in shallow hearths.
