How clean can the nickel industry become? | McKinsey
On top of that, with nickel being one of the most technically challenging metals to process and refine, and every operation being unique, further challenges will also be asset dependent (Exhibit 1). For miners, the type of ore deposit—sulfide or oxide (or laterite, further subdivided into saprolites and limonites)—defines the whole value chain.

Direct extraction of nickel and iron from laterite ores using …
So called "Carbonyl Refining Method for Laterite Ore" was developed by INCO up to the full scale pilot stage and included partial reduction of nickel and iron by CO/CO 2 gas mixture and direct extraction of nickel from ore in the form of nickel carbonyl. The product of the refining was forecasted as ferronickel with Fe/Ni ratio of 1.4/1.

leaching (HPAL), Caron process, and direct nickel process (DNi) are the most common processes to treat lateritic ore [4]. HL process can be processed at ambient temperature, but it is a kinetically slow process, and the yield is low compared to AL and HPAL [5]. AL requires 1 bar pressure and tem-perature in the range of approximately (50–90 °C).
