Adsorption phenomena in hydrometallurgy, 1 The uptake of copper, nickel and cobalt by oxide adsorbents in aqueous ammoniacal solutions
TL;DR: In this article, the uptake or adsorption of copper, nickel and cobalt by finely divided oxide solids in aqueous ammoniacal medium has been investigated experimentally in order to determine how adsorptive on leach residues can affect the recovery of leachable metals.

Extraction of copper, nickel and cobalt from sea nodules
TL;DR: In this paper, the sea nodules must be viewed primarily as ores of nickel and copper, with manganese treated as a storable byproduct, and pyrometallurgical processing to satisfy these conditions.

Non-ferrous metal recovery from deep sea nodules
TL;DR: In this paper, deep sea nodules containing non-ferrous metal values are selectively reduced to reduce manganic oxides to manganous oxide (MnO) and the non-frous metal value to the metallic state, and the selectively reduced nodules are then smelted to produce a molten metallic alloy.
