Abstract
A method and plant for gold recovery from any gold-bearing ore by low-temperature chlorination, wherein the finely-divided gold-bearing feedstock is chlorinated gaseous chlorine at a temperature of about 245° C. to form a highly volatile chloride compound, which after leaving a reactor is directed to a low-temperature nitrogen plasma unit having a temperature of 900-1100° C., wherein the said compound decomposes and turns into high-purity gold powder, which is cooled with gaseous nitrogen at a cooling reactor's inlet, which is equipped with a water chamber, and collected in a dumping hopper. Some embodiments allow recovery of high-purity 999.9 fine gold using an environmentally friendly, cost effective and inexpensive method implemented on an industrial scale.
