Hi monark
This would involve building a Nickel concentrator, then a refinery with reduction claves and SX and a crysrallizer which NW are currently doing (the crystallizer component). The all up cost of this would be in the vicinity of US$1B. I think its best we stay with Nickel west. The raw ore is nickel sulphide it has to be processed into nickel sulphate with all the equip I described.
