patent wolframite flotation ore concentration

• Zinc processingOres Britannica

  The most common method for accomplishing this concentration is to isolate the sulfide mineral from the impure constituents or gangue by flotation separation. In this process the ore initially is crushed to about 1.9 centimetres (0.75 inch) combined with water and ground to less than 0.1 millimetre in a ball mill.
