1. At present, the daily processing capacity is 200 per day, and the grinding treatment volume is strictly controlled between 8 tons and 9 tons per hour. The grinding overflow concentration is controlled between 30-35%, and the grinding fineness is controlled between -200 mesh and 80%-85%. The amount of processing and the degree of concentration must be strictly controlled: the ball miller measures the thickness of the shift 4 times per shift, registers it on the record book, and adjusts the grind concentration according to the measurement results and requirements.

Thickness measurement time per shift:

Day shift: 10:30 13:30 16:30 19:30

Night shift: 22:30 1:30 4:30 7:30

2. The preparation of the drug should be strictly in accordance with the preparation requirements, and the dosage of the drug-filled barrel should be prepared on time. The flow of the drug needs to be stable. During the normal production process, the flow of the pipe and the faucet should be checked to ensure that the faucet and the pipe are not blocked, and the agent can flow smoothly and quantitatively. .

Concentration and flow rate of the drug preparation: aluminum sulfate concentration 11% flow rate 25ml/L

Water glass concentration 6% flow rate 11ml/L

Silicone concentration 9% coarse selection 35ml / s sweep one, fine sweep 13 ml / s

Fine one, fine two, fine three 10ml/s fine four, fine five 8ml/s fine six, fine seven 5ml/s

Collector : Oleic acid: 5ml/s Saponified oleic acid: 40ml/s.

3. The agent of aluminum sulfate, water glass and silicone mixing tank needs to be stirred every hour for 5 minutes to prevent the precipitation of the drug and ensure the dissolution of the drug. The saponified oleic acid and oleic acid should be heated, and the slurry must be added after heating to hot. Pay attention to check the heating facilities to ensure the heating conditions. When adding oleic acid, you can't wait until the oleic acid in the tank is fast flowing. When the amount of oleic acid in the tank is half, add oleic acid immediately, otherwise the temperature in the tank can't be heated in time. Set the temperature.

4. During the flotation process, the slurry temperature control of the flotation tank must be in accordance with the temperature requirements, the rough selection temperature is controlled between 32-35 degrees, and the selected temperature is controlled between 25-28 degrees. The floatability of fluorite and calcium carbonate has a lot to do with temperature. Temperature control is important, not too high or too low, and needs to be controlled as required.

5. During the flotation process, the flotation operation requires no troughing, no troughing, and observing the foam phenomenon. The fluorite flotation foam is mainly composed of small dense and viscous foam, no large bubbles, no bubbles, and foam looks. Sticky, heavy, and foamed by hand. The color of the fluorite concentrate is dark yellow, similar to brown. If the foam is white, the amount of impurity calcium carbonate is large. When there is a bubble or vacuole in the foam, the first thing that comes to mind is that the amount of oleic acid and saponified oleic acid in the collector is not enough; the phenomenon of returning the pulp and not blistering indicates that the inhibitor is excessively gelatinous and needs to be appropriately reduced. The amount of glue used. The flotation process, the roughing, the surface scan mineral slurry to be controlled somewhat higher, so that most of the scraping up fluorite; six fine, fine seven, eight pulp refined to control some low level, additional water should be large.

6. Sample test and test 3 times per shift, take samples every hour, one sample every four hours, test and test.

White class: 9-12 13-16 17-21

Night shift: 21-24 1-4 5-9

Preparation method of saponified oleic acid:

The weight ratio of oleic acid to sodium carbonate is 3:1. The oleic acid is added to the upper small medicinal tank to be heated to a hot state, and sodium carbonate is weighed to one-third of the weight of the oleic acid, and added to the chemical tank to inject hot water to heat the sodium carbonate aqueous solution. The oleic acid switch is turned on during the stirring of the sodium carbonate solution, the flow rate is small, and the oleic acid is poured while stirring, and the mixture is thoroughly stirred.
