The whole process of flotation operation is roughly divided into rough selection, sweeping and selection, which are independent and close to the flotation process. Foam products in the selection area and rough selection area are generally sent to the selected area for one or more enrichment selections. The selected foam is the flotation final concentrate product. Dealing with the medium ore amount scraped in the sweeping area and the tailings product in the selected area has become a key issue that cannot be ignored in the whole flotation process. The control of the medium ore quantity is the focus of the whole flotation operation. In the control of the circulation of the mine, it is clear whether the amount of slurry in the whole flotation process is smooth; whether the foam tank can not run open, whether the foam fluidity is poor or not; whether the slurry level in the flotation tank is Higher scraping of slurry, the second must be judged by experience, whether it is caused by changes in the factors of the upper and lower operations and process conditions. The return of mines in a ship control is 40_80%. During the flotation operation, it is necessary to diligently observe the color of the foam, the thickness of the foam and the change of the sound of the scraped foam. It is also an inspection method for judging whether the ore selectivity and the difference and other process conditions are suitable. Gold River Ni ore sorting process, if the roughing operation the primary viewing real weight of foam, whether thick foam layer, the foam more uniform size whether or not the first groove to the groove is not most, whether the color of the foam thickness change significantly; scrape foam It is better to judge whether the indicator is squeaky in the foam tank. If the foam layer in the rough selection tank is thin, the number of foams is small and large, the change in the color of the foam is not obvious, and the foam in the flotation machine is turned into a slurry, and the foam scraped off from the liquid surface is filled with the slurry into the foam tank to make a sound. The flotation indicator is definitely worse. The observation of the color of the foam in the sweeping area and the selected area mainly determines whether the tailing grade and the concentrate grade are low and high. The color of the last row of foam is generally the best on the surface of the metal, indicating that the mineral separation is well-defined; the dead angle in the flotation cell is a glossy foam, indicating that the flotation agent and other process conditions are properly adjusted, which is beneficial to the tailings. Reduced. It is difficult to judge the high and low grades of the concentrates for flotation. It is only good to control the foam layer of the selected tanks above 200_300mm. It is strictly forbidden to select the operation to scrape the slurry into the concentrate products. Conducive to obtaining high-grade concentrate products. The flotation machine's aeration volume and the gate adjust the slurry surface, and control the thickness of the foam in the tank. At present, there are more questions in the flotation operation. In actual operation, some flotation workers are good at combining the aeration amount with the flotation gate, adjusting the slurry surface to form a thick foam layer, and adjusting the mineral surface to be foamed with the inflatable view, which cannot fully utilize the flotation Effect of machine and flotation process The inflation gate and slurry level control gate of the flotation machine should be flexible with the adjustment of the inflation gate, otherwise it will bring difficulties to the flotation operation. How to use the inflatable gate and the slurry level control gate, adjust the foam layer balance in the flotation tank with the inflatable gate, and pay attention to adjust the stirring action of the flotation machine. The motor belt of the flotation machine is tight; the slurry surface is discharged. Adjust the foam scraping without slurry, so that the flotation machine has a thick foam layer. If the efficiency of the flotation machine is not high, it should be inspected or repaired in time to maintain the efficiency of the whole row of flotation machines, creating better conditions for flotation operation and raising flotation indicators.

When recovering a variety of useful minerals in ore, the process of successive flotation of different minerals is called preferential flotation or flotation; the process of first separating all useful minerals and then separating them is called mixing-separation flotation. Industrial production must be based on the nature of the ore and the requirements of the product, using different prescriptions and flotation processes.
