Pardon. I was just giving a small indication of what the real use of nickel is, and why these mines existed way before the advent of any sort of hybrid cars, dont forget the pots and pans and cutlery we use everyday. Dont try to pretend now your some sort of metallurgist. The mining is a hole in the ground, and the same process is used to get that rock into Nickel element. The alloy it with steel to make a spoon or process it into a battery cell is only the last and small part of the chain.
Refined form and impurities in the same sentence, impressive stuff and boy what a paradigm that would be.
Nickel is the main metal you find in a NiMH battery.
Fox you dont dispose hybrid batteries, they are recycled, OEMs are giving a £100 or bounty for old batteries rather than dumping them.
Anyway we should all ignore that CO2 farce, for some reason its used it odd ways, its something we should ignore when driving our cars but it seems to matter massively when you come to making them. Why does the Co2 impact of refining petrol always get missed out?
