Mining is a process of research, exploration, extraction and processing of ores. This activity is fundamental for the socioeconomic growth of society, in our daily life several products are the result of mining, but, on the other hand, it is the cause of several environmental problems that we have. It can be divided into two fronts, open pit mining that is found near the surface ore and underground mining that is found at a greater depth. In Brazil we have mines in our 5 regions, there are about 3,354 mines, we export all types of ore such as: aluminum, copper, iron, tin, manganese, nickel, niobium and gold.
