In 2014, at Barrick's Goldstrike plant in Nevada, USA, the first gold bar was produced using thiosulphate solution. The gold-bearing ore was heated as a thick slurry of ore, air, water and limestone in large pressure chambers. The slurry interacted with thiosulfate and a fine, bead-like material that collects the gold.
