Has China shattered battery nickel's supply chain

China has turned the nickel market on its head after the world's biggest stainless-steel producer, Tsingshan Holding Group, this week agreed to supply about 100,000 tonnes of matte (containing approximately 65-75% nickel) to Huayou Cobalt and battery materials

JOM 0610: Cobalt

Also, SuperLig 176 can be used for the combined removal of copper and Fe(III) together with nickel from the cobalt electrowinning electrolyte. For cobalt recovery in a copper sulfide ore process, copper is removed via electrowinning and iron, zinc, and more copper are precipitated by

Electrowinning

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the

Application of Taguchi optimization for nickel

Low-grade laterite which has nickel content 0.5% has been processed using solvent extraction and followed by electrowinning process. Cyanex which diluted in toluene was used as an organic solvent to separated cobalt from nickel solvent. In this work, nickel solvent which frees from cobalt was processed using electrowinning. Electrowinning was conducted using batch recycle methods to ensure the

Electrowinning

Electrowinning from sulfate solutions is similar to that of electrowinning of nickel, and is discussed in Chapter 26. The major difference between nickel and cobalt electrowinning is that cobalt can be plated from sulfate solutions in cells with or without a separator between anode and cathode compartments.
