Opis

This book gives an overview of all the gold extraction processes along with their mechanistic study and environmental impact. Different approaches in gold extraction are discussed including traditional pyrometallurgy, amalgamation, leaching by cyanide or non-cyanide lixiviants and emerging bioleaching using micro-organisms, in detail.
