A Comparative Study of Ovacık Gold Ore with Thiourea and Cyanide Leaching

1996
Precious metals such as gold and silver have been recovered from their ores by cyanide for over a hundred years mainly due to its unique property in exploiting the low grade invisible gold with high recovery, being industrially proven process and its well-known chemical mechanism.
