There are nine tin-bearing ores found naturally in the earth's crust, but the only one that is mined to any extent is cassiterite. In addition to the ores themselves, several other materials are often used to process and refine tin. These include limestone, silica, and salt.Carbon, in the form of coal or fuel oil, is also used. The presence of high concentrations of certain chemicals in the ore may require the use of other materials.in is also combined with copper to form bronze and with lead to form solder. A tin compound, stannous fluoride, is often added to toothpaste as a source of fluoride to prevent tooth decay. The earliest use of tin dates to about 3500. in what is now Turkey, where it was first mined and processed.
The ubiquitous âtinâ can (many metal cans actually have no tin at all) provides information on both the. of an archaeological deposit and the activities that went on there. Large piles of coffee, evaporated. cooking-oil, and tobacco cans probably represent the kitchen area for a major work camp; fragments.
