A 2nd Edition of The Chemistry of Gold Extraction by (John.O. Marsden – C.I. House) is an extensively revised and comprehensively updated edition of the well-known reference first published in 1992. It provides the broad base of knowledge that is now required by all those working in the gold extraction and gold processing industries.
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
Jun 15, 2019· 1. Introduction. The use of dilute sodium cyanide or potassium cyanide solutions for the leaching of gold and silver from their ores was known as early as 1888 (Marsden and House, 2006).Cyanidation process has been the most successfully practiced method for gold extracting from ores over the past 100 years.
Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

Among free-milling gold ores placer gold is a special case, as there is no pre-treatment required for gold extraction. Gold can be extracted from placer ores using physical separation techniques, particularly through gravity treatment. In modern practice, concentrators use centrifugal force in order to liberate finer gold .
acceptable gold recoveries (Marsden and House, 2006). Other metals contained in the ores, such as cobalt, copper, and zinc, are also dissolved by cyanide and adversely affect overall gold recovery. Following extraction of the ore, the ore is either delivered to a crusher and reduced to a specific
