History of Mining Technology. In the beginning, miners used primitive tools for digging. Mining shafts were dug out by hand or using stone tools, making the entire process very lengthy. Eventually, the pick and hammer were replaced with fire to clear tunnels and reach greater depths at a faster rate.
Mining in Brazil is centered on the extraction of iron (the second largest global iron ore exporter), copper, gold, aluminum (bauxiteone of the 5 biggest world''s productors), manganese (one of the 5 biggest world''s productors), tin (one of the biggest world''s productors), niobium (concentrates 98% of the known niobium reserves in the world), and nickel.
Mechanization is the process of changing from working largely or exclusively by hand or with animals to doing that work with machinery. In an early engineering text a machine is defined as follows: Every machine is constructed for the purpose of performing certain mechanical operations, each of which supposes the existence of two other things besides the machine in question, namely, a moving
