· The governing method for gold ore processing has been cyanide leaching since the late 19th century (Marsden and House, 2006). After decades of active development of the process for various types of ores and concentrates, there are several different hydrometallurgical flowsheets for cyanide leaching. As ores differ greatly, the flowsheet needs to be tailored for the deposit in question. .
