Metal Recovery Processes
Gold electrowinning is commonly performed using steel wool cathodes and punched stainless steel plate anodes. General conditions include 2–4 V, 100–400 g Au/l input, 1–10 g Au/l output, 0.5–2% NaCN, 0.5–2% NaOH, and 50–90 °C with very low effciencies. Cells can be operated to produce a precious metals sludge that is easier to ...
