20221117Given these parameters, the later on water leaching of clinker provided extraction of 94.8% of copper, 91.5% of nickel and 82.3% of cobalt. The results of simultaneous thermal analysis and micrographs of particle surface after roasting lead to the conclusion that increasing the temperature is impractical in the technology under study.

Wong, et al used hydrometallurgy to extract valuable metals like gold, silver, selenium, tellurium from copper anode sludge. In this method, anode sludge without copper is used to extract silver, selenium, and gold. First, anode sludge without copper is leached into a roughly 4-9 molar nitric acid at 40-115 degrees Celsius.
