Nickel & Cobalt Recovery Intelligence

Predict selectivity and purity across Ni/Co separation.

Process overview

Nickel and cobalt recovery uses leaching, precipitation, and solvent extraction to separate and purify two chemically similar metals. Selectivity between nickel and cobalt is the central control challenge.

Why prediction matters

Ni/Co selectivity is sensitive to pH, reagent condition, and feed chemistry, and mis-separation is costly. Prediction links separation conditions to selectivity and product purity.

Key variables
