Embodiment 1
[0013] Put 50 grams of molybdenite ore dressing wastewater settling tank waste residue (containing 8.1% molybdenum, 5.7% tungsten, 1.2% nickel, 4.7% iron) and 100 grams containing 20% sodium hypochlorite, 10% sodium hydroxide solution together into 500ml Put the three-necked bottle in a constant temperature water bath at 60°C for a constant temperature reaction for 2 hours. After the reaction, use a Buchner funnel to filter it, then wash the insoluble matter with water, and mix the filtrate and washing solution into a beaker. Part of the water was evaporated to obtain a concentrate with a total metal content of 6.9%, code-named C-1.
Embodiment 2
[0015] 50 gram molybdenite ore dressing tailings (containing molybdenum 0.23%, tungsten 7.5%, nickel 0.7%, iron 6.8% through analysis) and 100 gram concentration are put into the three-necked bottle of 500ml together with the potassium hypochlorite of 25%. The three-necked bottle was placed in a constant temperature water bath at 80°C for constant temperature reaction for 4 hours. After the reaction was over, it was suction-filtered with a Buchner funnel, and then the insoluble matter was washed with water. The filtrate and washing liquid were mixed and put into a beaker to evaporate part of the water to obtain Concentrate with a metal concentration of 3.2%, code-named C-2.
Embodiment 3
[0017] Put 50 grams of molybdenite ore dressing wastewater sedimentation tank waste residue (after analysis containing 8.1% molybdenum, 5.7% tungsten, 1.2% nickel, 4.7% iron) and 200 grams of potassium permanganate with a concentration of 30% into a 500ml three-neck Put the three-neck bottle in a constant temperature water bath at 35°C for a constant temperature reaction for 6 hours. After the reaction, use a Buchner funnel to filter it, then wash the insoluble matter with water, mix the filtrate and washing liquid into a beaker and evaporate the part water to obtain a concentrate with a total metal concentration of 9.2%, code-named C-3.
