[0001] The invention relates to an extraction device, in particular to a novel energy-saving extraction device for extracting nickel sulfate from waste batteries. Background technique
[0002] Nickel sulfate has three types: anhydrous, hexahydrate and heptahydrate. Most of the commodities are hexahydrate, and there are two variants of α-type and β-type. The former is a blue tetragonal crystal, and the latter is a green monoclinic crystal. It loses six waters of crystallization when heated to 103°C. Soluble in water, slightly soluble in ethanol and methanol, its aqueous solution is acidic, slightly soluble in acid and ammonia. Extraction, also known as solvent extraction or liquid-liquid extraction, also known as extraction, is a unit operation that uses the different solubility of the components in the system to separate the mixture. That is to use the difference in solubility or partition coefficient of substances in two immiscible or slightly soluble sol...
