"Flotation is often used in a gold mill as a means of preconcentrating the gold bearing minerals prior to extracting the gold by cyanidation. Most of the mills that use this method use xanthate as one of the flotation reagents. Some of the xanthate is carried over into the cyanidation circuit as mineral coating and as flotation concentrate moisture. It is known that xanthate causes trouble in the subsequent cyanidation step but most information is very vague about the extent or nature of the problem. In view of this, a program was initiated two years ago to determine whether the exclusive use of xanthate in a flotation operation could have a significant effect on the efficiency of the subsequent cyanidation step"--p. 66. gccst Gold gccst Processing Honeywell, W.
