The Metallurgy of Cyanide Gold LeachingAn Introduction

   The Metallurgy of Cyanide Gold LeachingAn Introduction. Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide no other process has yet been proven to be an economic viable alternative.
