How Aluminum is Produced

2020-10-30 · Aluminum is formed at about 900°C, but once formed has a melting point of only 660°C. In some smelters this spare heat is used to melt recycled metal, which is then blended with the new metal. Recycled metal requires only 5 per cent of the energy required to make new metal.

Causes, Effects and Solutions for Mining

Many mining companies, especially in poor countries, deposit the by-products of mining near rivers or lakes in order to get rid of them. However, through rain, these by-products which often contain harmful elements may be washed into the rivers, lakes or also into the soil. This in turn will also lead to contamination of our drinking water.
