| titleOfInvention | Beneficiation method for tungsten polymetallic ore |
| abstract | The invention discloses a beneficiation method for tungsten polymetallic ore. The beneficiation method comprises the following steps of (1) grinding the tungsten polymetallic ore to form powder, (2) adding the powder to magnetized water to form ore pulp, then, adding regulators, foaming agents and first collecting agents, feeding in air to form a first foam layer, obtaining tailings after removing the first foam layer, (3) adding first inhibitors, activators and second collecting agents to the tailings, feeding in air to form a second foam layer, collecting the second foam layer to obtain white tungsten rough concentrate, and (4) concentrating the white tungsten rough concentrate till the mass of the white tungsten rough concentrate ranges from 55% to 70% of the mass of the white tungsten rough concentrate before concentration, heating the white tungsten rough concentrate to the temperature which ranges from 85 DEG C to 95 DEG C, adding second inhibitors, feeding in air to generate a third foam layer, and collecting the third foam layer to obtain white tungsten concentrate. According to the beneficiation method for the tungsten polymetallic ore, the magnetized water is used in the technological process, difference between floatability of the white tungsten ore and floatability of calcium minerals can be increased, flotation separation of the white tungsten ore and the calcium minerals such as fluorite and calcite is achieved, and the recovery rate of the white tungsten ore is increased. |
