The mining and minerals industry Africa has the largest minerals industry in the world. The continent is home to vast reserves of industrial diamonds, Platinum Group Metals (PGM), phosphate rock, bauxite, cobalt, zirconium, vermiculite, gold, copper, iron ore, lead,
In mining and minerals processing and extraction, there are many stages used covering a wide variety of different chemical reactions. Process stability is the key factor to reach the maximum recovery rate.
In 2016, minerals extracted in Québec came from 27 active mines and close to 530 surface mining sites (Institut de la statistique du Québec).The value of mineral shipments reached $8.11 billion, a 7.8% increase over 2015. The main metals mined are, in decreasing order of shipment value, gold, iron, nickel, titanium, niobium, copper and zinc.
