what raw minerals are needed to make tin cans
The raw material of the aluminum beverage can is, of course, aluminum. Aluminum is derived from an ore called bauxite. U.S. aluminum producers import bauxite, primarily from Jamaica and Guinea.wenty-five percent of the total American aluminum supply comes from recycled scrap, and the beverage can industry is the primary user of recycled material. The energy savings are significant when used cans are remelted, and the aluminum can industry now reclaims more than 63% of used cans.
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.
