Nickel waste tailings are produced during the hydrometallurgical leaching of nickel – cobalt ore slurry with concentrated sulphuric acid. They are classified by the Toxicity Characteristic Leaching Procedure (TCLP, US EPA Method 1311) as hazardous materials owing to the extremely high levels of leachable nickel (about 400 mg/l).
