Lime use in gold processing – A review

A significant body of scientific literature has been devoted to the industrial use of cyanide in gold processing (Adams, 1990; Marsden and House, 2006), in contrast to the dearth of publications on the use of lime in this important industry. This review, therefore, explicitly focuses on lime use in gold processing applications.
