Advanced industrial-scale recycling of nickel waste alloys: a driver for circular economy objectives

An eco-friendly electrochemical method of nickel alloy waste leaching was developed for circular economy. The nickel concentration was 72.11 g/L in 100 g/L HCl after 90 A·h, 60 °C and 5 A/dm2 current, while 37.37 g/L nickel was obtained in 100 g/L H₂SO₄ under these conditions. Th...
