Nickel Solvent Extraction Technology BASF

Nickel laterite ores are becoming an increasingly important source of nickel and cobalt. BASF solvent extraction reagents are used in a nickel production plant, Queensland Nickel Inc. (QNI), to extract nickel from ammonia solutions. LIX® 87QN reagent was developed to fit into a QNIdeveloped nickel recovery process based on a modified Caron process.

Magnesium Removal from Concentrated Nickel Solution by ...

Solvent extraction technology has obvious advantages in metal separation and purification which has been widely used in nickel cobalt industries. Magnesium separation from nickel in a synthetic releach solution by solvent extraction using Cyanex 272 (bis (2, 4, 4trimethylpentyl) phosphinic acid)) and its analogue of P 507 (2ethylhexyl phosphonic acid mono2ethylhexyl ester) was studied.

Chemistry of Nickel Chemistry LibreTexts

Nickel oxide is a powdery green solid that becomes yellow on heating. It is difficult to prepare this compound by simply heating nickel in oxygen and it is more conveniently obtained by heating nickel hydroxide, carbonate or nitrate. Nickel oxide is readily soluble in acids but insoluble in hot and cold water.
