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.
Aluminum is all around us, in almost every rock, plant, and animal. It is the third most plentiful element in the earthâs surface, after oxygen and silicon, and its compounds make up about 15 percent of the weight of the earthâs crust.But nowhere in nature is aluminum found in a pure form, itâs always mixed with other elements.Some parts of the earthâs crust contain large amounts of aluminum compounds, and these regions are mined for their aluminum ore. The most common aluminum ore is called bauxite.luminum is used for foil because it is light, weighing less than half as much as iron or copper, and can be pressed into very thin sheets. Aluminum is a good conductor of electricity and a good insulator against heat and light, which makes it perfect as a food wrap.
