Cyaniding the Buckhorn clay

The Buckhorn, Nevada, gold mine is peculiar in being a shallow kaolinized mass of material with basalt walls, having no direct connection with any of the usual gold bearing rocks, the average ore containing 16% water of hydratum. the cyaniding of this hydrant clayey material offered unusual difficulties compared with the usual gold quartz ore of Nevada. The ore body was thoroughly developed; then the mill was built according to the latest cyanide practice, with such changes as was thought the peculiar nature of this ore demanded. Upon starting the mill, the ore proved more difficulty to handle than had been anticipated. It is hoped that an account of how these difficulties were met may prove of interest to anyone having a clayey ore to handle and the profession in general --page 1
