Gold Tellurides are Soluble in Cyanide
AT last year's Annual Meeting a paper by Haultain and Johnston was presented entitled Is the Gold in Tellurides Soluble in Cyanide? Since then the writer has continued the study of various phases of this problem. Samples and specimens of ore from some of the Kirkland Lake mines have been studied and non gold-bearing tellurides have been found in these that are not soluble in ordinary mill solutions. Samples of tailings, both old and recent, from this district have been examined wit)l apparatus and methods that have proved very successful in detecting the presence of extremely minute quantities of tellurides.
