Description

Separation and recovery of nickel, cobalt, or iron in a synthetic solution with two components similar to a solution from manganese nodules leached by sulphuric acid were investigatdd as a function of the concentration of collectos as diethyl-and dimethyl-carbamates or of pH. Nickel and iron in each quasileach solution were collected over 90%, but cobalt was collected in a little lower percent. Iron and nickel or iron and cobalt in the two constituent solution have to some extent a possibility to separate each other using the above mentioned collectors around pH=1. Separation of iron and nickel is better than that of iron and cobalt on the basis of the separation index. Separation of iron and cobalt is improved around pH=2.5. Flotation products from quasi-leach solution may be identified as metalcollector complexes by IR spectra. The conditional stability constant of metals with collector explains a tendency in the flotation recovery of these complexes as a function of pH.
