Justification sequence dissolution of cobalt and nickel mineral by unconventional thermodynamic method
The article shows the forecasts of different reactivity of the mineral cobalt and nickel and the choice of effective reagents for opening minerals cobalt and nickel, copper and other metals from cobalt-nickel containing raw materials using unconventional thermodynamic method, in particular, the average atomic formation energy of minerals ∆rG° and the reduced value of new chemical affinity of reaction oxidation ΔrG°/n. These studies allow to choose of the optimal conditions for the dissolution of minerals cobalt and nickel with the least expenditure of time.
