Tungsten Ores. Soda ash or sulfuric acid is usually added for pH control. Acid is frequently preferred for those ores containing pyrrhotite. However, its use with calcite gangue ores will result in the formation of calcium sulfate, which may float with and dilute theFigure 8 shows a tungsten flotation flowsheet.
