Nickel and copper were co-extracted from ammoniacal ammonium sulfate leach liquors (pH-9 5) with LIX 64N extractant in a laboratory-size mixer-settler continuous circuit Three extraction stages resulted in 99-pct extraction of nickel substantial copper extraction and essentially no
The nickel and ammonia solution contains 2:2 ratio of nickel to ammonia (molar) which is roughly 50 grams nickel per liter of solution The nickel-ammonia solution is then reduced with hydrogen in autoclaves adding a a small amount of ferrous ammonium sulphate This solution is heated to 250 deg F at 350 PSI in a hydrogen atmosphere
The nickel ore is sent to the nickel refinery where a complex set of reactions is carried out These include leaching in autoclaves using ammonia heated to around 200 deg F
Mining has always been an environmentally disruptive activity but contemporary extractive industries are located in some of the most ecologically sensitive forests in the boreal and the tropics Oil gas and mineral extraction account for an estimated 7% of global deforestation in the subtropics with increasing exploration and development taking place in the Amazon and Congo basins
