The flotation process consists of different flotation operations. Divided into rough selection, selection, and sweeping operations. Rough selection: The first operation of the slurry after reconciliation into flotation is rough selection. Featured: The operation of re-flotation of the rough selected foam product is called selection. Sweeping: The operation of continuing the flotation of the remaining tailings is called sweeping. 2. What is the relationship between flotation process selection and ore properties? The choice of flotation process is related to the nature of the ore and the requirements for the quality of the concentrate. The nature of the ore is very important. When selecting the process, consider: 1) the particle size and symbiotic characteristics of the useful minerals in the ore; 2) the muddy condition of the ore in the grindstone; 3) the floatability of the mineral; 4) the mineral Composition and content of soluble salts; 5) grade of ore; 6) degree of oxidation of ore. 3. What kind of minerals should be treated with one or two stages of flotation? The flotation process can be one-stage, two-stage or multi-stage. The number of stages in the flotation process is mainly related to the dip-dyeing characteristics of useful minerals in the ore and the muddy conditions of the ore during the grinding process. The general flotation process is to grind the ore directly to the required particle size and then perform flotation to obtain the final product without re-grinding any product. Ores that are uniformly impregnated with useful minerals are generally suitable for a flotation process. The second stage flotation process is also called the stage flotation process. The main purpose of the stage flotation process is to avoid the pulverization and mud formation of useful minerals and gangue in the ore, so that the gangue is discharged as tailings at a coarser particle size. Sometimes, in order to select some of the coarse-grained concentrates that have been separated by monomer. Therefore, the financial security generally more complex gold ore treatment useful minerals using stage flotation process. 4. How to determine the number of concentrates and sweeps in the flotation process? After determining the ore flotation principle process, it is also necessary to solve the internal structure of the flotation process, that is, to determine the number of selections and sweeps in the process. The selection and selection of the number of sweeps depends on the grade of the ore, the floatability of the useful minerals, and the requirements for the quality of the concentrate. When the ore grade is low, the floatability of the useful mineral is good, and the quality of the concentrate is high, the selection should be strengthened, that is, the selection time is lengthened and the number of selections is increased. When the ore grade is high, the useful minerals are poorly floatable, and the quality of the concentrate is not high, the sweeping should be strengthened, that is, the sweeping time is lengthened and the number of sweeps is increased. 5. How to deal with the middle mine in the flotation process? The tailings and sweeping foam products of each selected operation that are obtained in the flotation process and require further processing are called medium mines. The treatment method of the medium ore should be based on the content of the continuum, the floatability of the useful minerals and the requirements for the quality of the concentrate. There are four common methods for handling medium mines: 1) Return the medium mine to the appropriate location at the front of the flotation cycle; 2) returning the middle mine to the grinding and grading cycle; (mainly the middle mine composed of continuous organisms) 3) Separate the medium ore; (mainly the middle mine consisting of complex, easily oxidized, difficult to float ore) 4) The medium mine is no longer flotation, but is treated by other methods. (mainly fearing the loss of a large amount of metal, the medium ore is treated by pyrometallurgical or chemical methods, or not treated as low-grade concentrate sold) Robotic Glue Dispensing,Auto Glue Dispenser,Glue Dispenser Syringe,Automatic Epoxy Dispenser CIXI TIANHAO ELECTRIC CO.LTD , https://www.nbtianhao-auto.com
