Sodium silicate was somewhat effective in causing a differential or selective flotation of copper as chalcopyrite from pyrite by keeping pyrite from floating Sodium hydroxide and sodium sulfide gave in most cases a distinct separation of sphalerite from chalcopyrite i e a high copper and low zinc by suppressing the flotation of sphalerite
