Since all tungsten ores are very friable and slime easily, concentration must take place as soon as the mineral has been liberated by either crushing or grinding methods. Regardless of the care taken in the selection of the flowsheet, a certain portion of the tungsten is going to be slimed, both during the mining and the milling process.
