"Flotation of the oxidized ores of zinc" by Fred Henry Bunge

"There is no satisfactory method of concentrating the finely disseminated oxide ores of zinc. Gravity methods of concentrating such ores may be used for coarsely crystalline materials in which the zinc material is free at approximately 10- to 35-mesh or coarser. In addition, gravity methods of concentration do not give a satisfactory separation on those ores in which the gangue mineral is small.
