Gold extraction by chlorination using a pyrometallurgical. The objective of this research was, on one hand, to study gold extraction from an alluvial material, through a pyrometallurgical process, using chlorine gas as a reactant, and, on the other hand, to characterize the initial material and chlorination residues, using X-ray fluorescence (XRF), X-ray diffraction (XRD) and scanning

2009-3-1 The direct chlorination of a pure gold was also studied up to a temperature of 1223 K.These experiments demonstrated that the precious metal is not attacked at that temperature, in agreement with the literature, which indicates that the reaction of direct chlorination of gold is produced at high temperatures (Panias and Neou-Syngouna, 1990).The fact that gold chlorination is reached at lower ...
