Sulfide Mining Sierra Club

The mining of copper/nickel sulfide ores is a toxic type of mining that is risky to our environment, our workers and communities, and local economies. Mining sulfide rock releases acid and toxic metals and contaminants that pollute rivers and groundwater for hundreds of years, long after the profits are spent and the products buried in landfills.

Nickel Mining Like its 1864 Ahead of The Herd

Today, nickel sulfide deposits are the primary source of mined nickel about 58% of world’s nickel production come from nickel sulfide and 42% of mined nickel comes from nickel laterite deposits. The majority of today’s nickel is produced from sulphide deposits because they are easier and cheaper to mine and process than lateritic ore.

The nickel-bearing sulfide deposits typically consist predominantly of pyrrhotite (F6t-4'S) and associated pentlandite [(Fe, Ni) 988] and chalcopyrite (CuFeS2). Many of the deposits contain minor but re­ coverable amounts of platinum metals, cobalt, and selenium.

Global trends and environmental issues in nickel mining

The known resources of nickel sulfide ores are quickly diminishing; to satisfy future nickel demands, nickel laterite deposits are now being investigated as an alternative. The use of classic mineral processing techniques to economically extract nickel and prepare high-grade ferronickel from low-grade nickel laterite entails numerous challenges.
