This warrants the first conclusion: Statistically Eq. ( 4) is the best model for mines with milling/flotation. On the basis of this, an ore grade of, and % at 300 m of depth results in an energy cost of 60, 127 and 447 MJ/kg for underground mines, and 52, 95 and 255 MJ/kg for surface mines, respectively.

• Finished nickel production from Sudburysourced ore decreased 9% q/q, as mine and mill maintenance activities in Q3 limited finished production in Q4. During Q4, Sudbury mines achieved the highest quarterly production rates since 2Q19, which is expected to be translated into better finished nickel production in 1H23.

October 4, 2022. Nickel deposits come in two forms: sulfide or laterite. About 60% of the world's known nickel resources are laterites, which tend to be in the southern hemisphere. The remaining 40% are sulfide deposits. The main benefit of sulfide ores is that they can be concentrated using the fairly simple flotation technique.
