Kongsberg Silver Mines
The silver mines of Kongsberg, in Buskerud county in Norway, constitute the largest mining field in Norway, with over 80 different mines. It was the largest pre-industrial working place in Norway, with over 4,000 workers at its peak in the 1770s and supplied over 10% of the gross national product of the Danish–Norwegian union during its 335-year-long history: over 450,000 man-years were expended in the production.
Cerro Matoso mine
The Cerro Matoso mine in northwest of Colombia is one of the largest open-pit ferronickel mines with the highest-grade lateritic nickel ore deposits in the world. The largest mine of South America, containing the largest nickel reserve in Colombia has been operated by Anglo-Australian multinational BHP Billiton since 1980. 
After 4 decades of mining with heavy metal pollution affecting especially local indigenous Zenuand Afro-Descendant residents the first study of a public health impact was published in 2015. BHP spun off Cerro Matoso in a new company. In 2018 the Constitutional Court of Colombia has ordered the mine to pay damages to local communities.
