The invention discloses a comprehensive
recovery and
beneficiation process for
wolframite and
scheelite and associated valuable metals of
wolframite and
scheelite. The comprehensive
recovery and
beneficiation process comprises the following steps:
tungsten-
molybdenum-
copper polymetallic ore is crushed, ground and floated to obtain
copper-
molybdenum mixed rough concentrate and
copper-
molybdenum flotation
tailings; the copper-molybdenum mixed rough concentrate is subjected to ore
grinding and molybdenum floating and copper inhibiting separation, and molybdenum concentrate and copper concentrate are obtained; the copper-molybdenum flotation
tailings are graded, and oversize products and undersize products are obtained; the oversize product is subjected to
gravity separation, and
gravity separation rough concentrate and
gravity separation tailings are obtained; the reselected rough concentrate is subjected to ore
grinding and flotation, and
tungsten concentrate 1 is obtained; and the undersize products and the gravity separation tailings are subjected to ore
grinding and flotation, and
tungsten concentrate 2 is obtained. According to the
beneficiation process, over-crushing of the ore can be effectively avoided,
monomer dissociation is gradually achieved, and qualified tungsten concentrate, molybdenum concentrate and copper concentrate are obtained on the premise that the
recovery rate is guaranteed, so that valuable elements in the ore are fully recovered, and the comprehensive
utilization rate of resources is increased.
