The Tin Manufacturing Process

in Process

Tin is one of the most commonly used materials for coating purposes.  Due of its resistance to corrosion, Tin is often used as a coating agent.  Tin is also combined with other metals such as copper to produce other metals such as Bronze.  Tin in some other form is used to prevent the rotting of teeth.

Tin is manufactured by the process of extraction from a ore called cassiterite.  The first step in the tin manufacturing process is called mining.   Initially, gravel is made to come to the surface using a floating dredge. This gravel containing cassiterite is then passed through a set of filters to remove the tin from the gravel.

Once the tin is removed from the gravel the next process of concentrating the tin in cassiterite begins.  Here the separated tin is allowed to pass through a set of screens, during which other elements present in the tin is removed in a step by step manner.  After this, the tin is then washed in a tank and some other elements are added to the tin, so that the tin moves up the water tank and gets collected at the surface. The surface collected tin is then dried.

The dried tin with the added elements are now passed through a set of screens again to remove unwanted materials. The next step in the tin manufacturing process is the process of smelting.  In this process, tin is heated in a furnace with coke or oil to very high temperatures until it becomes a slag. The tin slag is again re-heated in a furnace to get rid of the impurities present in the tin slag. After the smelting process, the tin is again subjected to one more round of heating, to separate iron from the tin.

After separating iron from the tin, it is again heated, boiled and refined to get rid of the additional impurities. Thus the tin that is extracted is almost pure and can be used for commercial purposes. Tin is used for a variety of commercial purposes. Tin is used as a food container to store food.  As tin contains the necessary chemical elements to preserve food particles, it is very helpful in preserving food.  One form of tin called stannous fluoride is one of the ingredients in the toothpaste.  Because of these benefits of tin, other metals which cannot be used alone for commercial purposes are often combined with tin. Metals combined with tin are widely used for storage purposes across various industries.
