inorganic chemistry - Separating nickel coin into …
I will give you a stone method for the separation of the two metals. If you want to separate the metals then I would use the following method, I would dissolve the coins by immersing them in hydrochloric acid with air present. This will convert the nickel / copper alloy into a solution of copper chloride and nickel chloride.
Nickel-Cobalt Separation - Innovation Metals Corp
Introduction Following the initial development of IMC’s RapidSX™ process for the separation of rare-earth elements (REEs), the company turned its attention to the separation of nickel (Ni) and cobalt (Co) from a pregnant leach solution (PLS) produced from a ‘real-world’ bulk sample of Ni-laterite ore. The testing was completed first at the bench scale, and […]
How can I seperate copper from nickel? - …
How can I seperate copper from nickel? ... flotation and magnetic separation. Besides, leaching one or two metals from the matte also can be used to separate the copper and nickel.
Separation of copper(II), cobalt(II) and nickel(II) …
The separation of copper(II), cobalt(II) and nickel(II) from aqueous chloride solutions by polymer inclusion membranes is presented. The tertiary amines, i.e. tri-n-octylamine (TOA) and triisooctylamine (TIOA) have been applied as the ion carriers in membrane.The source phase was an aqueous HCl solution containing Cu(II), Co(II) and Ni(II).
Separation of copper from nickel in sulfate …
Mechanochemical activation was used to the separation of copper and nickel. • The CaCO 3 was effective to separate copper from nickel in sulfate solutions.. Over 99% Cu(II) ions were precipitated, while 99% Ni(II) ions remained in solution.

Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, …
Mineral processing - Wikipedia
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
Copper & Nickel Solvent Extraction
Nickel and copper were co-extracted from ammoniacal ammonium sulfate leach liquors (pH-9.5) with LIX 64N extractant in a laboratory-size mixer-settler continuous circuit. Three extraction stages resulted in >99-pct extraction of nickel, substantial copper extraction, and essentially no cobalt extraction from leach liquors.
