Copper-Nickel Ore Processing 911 Metallurgist

07/11/2019 The separation of copper from nickel is based on the fact that there is an appreciable difference in the pH at which the two metals are extracted. Copper can be extracted, with very small amounts of nickel, at pH 6.0 to 6.5, while nickel is extracted from the copper raffinate at pH 8.0 to 8.2. These pH values refer to the pH of the aqueous phase entering solvent extraction; the corresponding

Copper-nickels The addition of nickel to copper

Copper-nickel alloys have excellent resistance to marine corrosion, strength and durability. The two main alloys are 90/10 (90% copper, 10% nickel) and 70/30 (70% copper, 30% nickel). The 70/30 is the stronger and has greater resistance to seawater flow, but the 90/10 will provide good service for most applications and, being less expensive, tends to be more widely used. Both alloys contain

Liberating Copper and Nickel: A True Story

Many copper refineries that are embracing 'zero discharge' are abandoning evaporization and crystallization, electing instead for an Acid Purification Unit (APU) to treat the decopperized nickel solution using ion exchange to recover the sulfuric acid and produce a de-acidified nickel solution. Now that the sulfuric acid has been isolated from the bleed electrolyte, the concentrated and
