Cyanide leaching is the most common method used for production of silver from gold/silver ores. Silver (and gold) can be recovered from pregnant leach solutions (PLSs) using Merrill-Crowe process (zinc cementation) and activated carbon adsorption. Du

Today, the most common (>%90) method preferred for production of gold from ores is cyanide leaching. Cyanide leaching with its well-known chemistry has been used industrially since the late 19th century. Restrictions have come into force particularly

Cyanide leach solutions produced from gold/silver ores can be contaminated with zinc due to the gold/silver cementation in Merrill-Crowe process and/or the dissolution of zinc minerals present in the ore. Zinc levels in cyanide solutions should be co
