How to Extract Gold from Tailing?-mining-pedia

Mar 22, 2021  When the gold inclusions in the tailings contain both iron oxide and silicate (quartz), it is difficult to recover the gold in the two inclusions at the same time by using the above method alone. At present, the main methods for extracting gold from two inclusions at the same time are molten chlorination method and iron smelting method.
