The life of Ni
The world''s nickel resources are currently estimated at almost 300 million tons. Australia, Indonesia, South Africa, Russia and Canada account for more than 50% of the global nickel resources. Economic concentrations of nickel occur in sulphide and in laterite-type ore deposits. Despite the fact that nickel mining has significantly increased over
From 1953 to 1958 Nickel Rim mines operating around Sudbury, Ontario deposited their mine tailings in an impoundment near the mine. The water in the impoundment was later tested and found to have low pH and high concentrations of iron, sulphur and dissolved metals such as aluminum and nickel. This is due to the oxidation of the tailings (usually sulfide minerals like pyrrhotite).
