At room temperature, tin is quite resistant to the impact of air or water, as a thin oxide film forms on the surface of the metal. In air, tin starts to oxidize at a temperature of over 150 °C: Sn + O 2 → SnO 2. [6] Antoine Lavoisier explored this experiment with similar results time later. [7]
In 2015, the value of coal, metals, and industrial minerals mined in the United States was US$109.6 billion. 158,000 workers were directly employed by the mining industry. [ 1 ] The mining industry has a number of impacts on communities, individuals and the environment.

According to a 2021 report from The Nature Conservancy, the average daytime temperature in Illinois has increased by 1 to 2 °F (0.6 to 1.2 °C) over the historical average in the last 100 years. Additionally, the nighttime minimum temperatures are rising at a faster rate than the daytime high temperatures.
Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within the ore, into soluble salts while the impurity remains insoluble. These can then be washed out and processed to give the pure metal; the materials left over are commonly known as tailings .
