Black tungsten thin clay beneficiation methods

One kind of black tungsten carbide inserts fine mud beneficiation methods. Its features are: 1) To re-elect Desliming: won re-election and re-election concentrate tailings; 2) sulphide flotation: Getting sulfur sulphide flotation concentrate and tailings; 3) black tungsten flotation: the sulphide flotation tailings adjusting agent is added sodium carbonate, sodium silicate, aluminum sulfate, lead nitrate, adding flotation sulfated oleic acid soap, after a second roughing, selection of 2 to 3 times, 2 to 3 times a sweep sorting, flotation concentrate was mixed black and white and black and white tungsten tungsten flotation tailings. This method is characterized by: black tungsten fine mud recycling process is simple, black and white mixed flotation process is stable tungsten, tungsten recovery, pharmaceutical and low cost. This process applies to WO ↓ [3] content of 0.10 to 0.50%, less than 30 micro-grain level WO ↓ [3] ≥ 60% share of the metal tungsten fine white clay.
Method, which is characterized by the following steps accordingly: a) To re-elect Desliming: black tungsten fine mud after roughing, selection, sorting sweep the election were re-elected and re-elected concentrate tailings; 2) sulphide float Select: gravity concentrate concentrated to 30 to 45% concentration, to obtain sulfur sulphide flotation concentrate and sulphide flotation tailings; 3) black tungsten flotation: the ore per ton of fine mud gauge, the vulcanization flotation tailings adjusting agent is added 100 to 500 grams of sodium carbonate, sodium silicate 500 to 5000 grams, 100 to 2000 g of aluminum sulfate, 50 to 1000 g of lead nitrate, stirred for 1 to 10 minutes; add oil collector sulfation 50 to 500 g acid soap, stirring for 1 to 10 minutes; through a second roughing, selection of 2 to 3 times, 2 to 3 times a sweeping election, flotation concentrate was mixed black and white and black and white tungsten tungsten flotation tailings.
