Nickel recycling

Nickel in a circular economy. The concept of a circular economy is generally understood to be a regenerative system in which resource input and waste, emission, and energy leakage are minimised by slowing, closing, and narrowing energy and material loops.This can be achieved through long lasting design, maintenance, repair, reuse, remanufacturing, refurbishing, and recycling 1.

How to Recycle Batteries

To some extent, nickel from NiMH can also be recovered economically if available in large quantities. New recycling methods are being developed that retrieve the metals by electrolysis, also knowns as chemical recycling. The process is said to be more cost effective and produces higher yields with less pollutants than traditional smelting. Get price

processing techniques of nickel ore

nickel processing - Mining - With nickel found in two radically different types of ore, it is not surprising that the mining methods differ. Sulfide deposits are usually mined by underground techniques in a manner similar to copper, although some deposits have been mined using open pits in the early stages. Get price

Processing of Iridium and Iridium Alloys

Iridium and its alloys have been considered to be difficult to fabricate due to their high melting temperatures, limited ductility, sensitivity to impurity content and particular chemical properties. The variety of processing methods used for iridium and its alloys are reviewed, including purification, melting, forming, joining and powder metallurgy techniques. Get price

Electroplating Process Steps

For nickel plating, the solution is made of 180 – 240 gm of nickel sulfate, 36 gm of nickel chloride and 24 gm of boric acid per 1000 cc of solution. The anode is of pure nickel. Nickel does not deposit well on iron and steel articles. Therefore, the article is first coated with a film of copper and then nickel is deposited on the copper plating. Get price

Metal Finishing–What Types of Finishes Are There?

Metal plating uses chemical baths to coat or alter the surface of substrates with thin layers of metal such as zinc, nickel, cadmium, or chromium. The electroplating method generates an electric current to coat the substrate, while electroless plating employs an autocatalytic process in which the Get price
