Flotation separation of copper–molybdenum

01-11-2015  The flowsheet of the copper–molybdenum ore bulk flotation test is described in Fig. 2. Six hundred grams −2 mm ore was ground to 70% −74 μm in a Φ 160 × 180 mm ball mill. The bulk flotation tests were conducted in a XFD flotation cell, with cell volumes of 1500 mL for rougher flotation and 500 mL for cleaner flotation.
